The 39-year-old forward, who has three years remaining on his contract, told Slovakian newspaper Novy Cas in May his hockey career was over because of a skin disorder.
Arizona also received forward Vinnie Hinostroza, defenseman Jordan Oesterle and a third-round pick in the 2019 NHL Draft. Chicago acquired forwards Marcus Kruger and Jordan Maletta, defenseman Andrew Campbell, the rights to unsigned draft pick MacKenzie Entwistle, and a fifth-round pick in the 2019 draft.
"I will not play hockey anymore," Hossa told the newspaper. "I have a valid contract with Chicago for the next three years, but I have only one health and it does not allow me to return."
Hossa signed a 12-year contract with the Blackhawks on July 1, 2009. Because his contract does not expire until after the 2020-21 season, he could not officially announce his retirement, which would have resulted in salary cap ramifications for Chicago.
The Coyotes are responsible for the salary cap charge associated with the final three seasons of Hossa's contract. They feel they got two players whose production will go up.

"You get the question a million times, 'What have you learned from [the] Vegas [Golden Knights]? What have you learned from Vegas?'" Arizona general manager John Chayka said. "It's obvious there are a lot of players in this league, when given greater opportunity, can really perform and make an impact. As a staff, we tried to evaluate the most undervalued players in the League. These two guys that we got are guys that we spent a lot of time talking about in scouting meetings, really breaking them down, analyzing them and researching them.
"... [Hinostroza] is a right shot, he's got some versatility, he's got a ton of speed and skill to fit in with our system and what we're trying to do. ... Getting Oesterle, a pick swap, those are the things that add up and make sense for our group."
Hossa, selected by the Ottawa Senators with the No. 12 pick of the 1997 NHL Draft, is 54th in NHL history with 1,134 points (525 goals, 609 assists) in 1,309 games with the Senators, Atlanta Thrashers, Pittsburgh Penguins, Detroit Red Wings and Blackhawks. He won the Stanley Cup with the Blackhawks in 2010, 2013 and 2015.
"Today is another example of the leadership Marian has displayed as a member of the Chicago Blackhawks organization," the Blackhawks said in a statement. "When we approached him to discuss the idea of him waiving his no-move clause to allow us to make this move, it became clear this was a difficult thing for him to consider.
"After the success he has had in a Blackhawks jersey, the friends he has made throughout the organization and the fact his heart will always be in Chicago, the thought of disassociating in any way from the team he has come to love was not something he really wanted to give any thought to at all. But as the consummate team player, he did what he has always done. He did what the team needed him to do in order to succeed."

Hossa's last NHL game was against the Nashville Predators in Game 4 of the Western Conference First Round on April 20, 2017.
"Since then, I haven't (put my gear on)," Hossa told the newspaper. "Not even a single one time. I've been on the ice couple of times just to skate with my daughters, but I haven't had my hockey gear on."
Hossa was on long-term injured reserve last season, and Blackhawks general manager Stan Bowman said April 10 that a return for Hossa appeared unlikely.
"[Hossa's] physical condition hasn't improved, so at this point there's no indication he's going to play next year either," he said.

Hinostroza, 24, had 25 points (seven goals, 18 assists) in 50 games with the Blackhawks last season. It was his most extensive NHL action since being selected by Chicago in the sixth round (No. 169) in the 2012 NHL Draft. He had 39 points (13 goals, 26 assists) in 106 games in three seasons with the Blackhawks.
"In Chicago, there are just so many of those guys that are already established in the city and the organization," Hinostroza said. "I'm really excited about the opportunity that I'm going to be given and I'm going to keep earning with hard work. I'm not going there thinking anything is going to be given to me."
Oesterle, 26, had 15 points (five goals, 10 assists) in 55 games. In four NHL seasons with the Blackhawks and Edmonton Oilers, he has 21 points (five goals, 16 assists) in 80 games.
Kruger, 28, returns to Chicago after he had six points (one goal, five assists) in 48 games with the Carolina Hurricanes last season. The Blackhawks traded Kruger to the Vegas Golden Knights on July 2, 2017, and Vegas traded him to Carolina on July 4. The Hurricanes traded him to the Coyotes on May 3, 2018.
"Now I have the chance [with Chicago again] and I really want to do something good with it," Kruger said. "I couldn't think of a better place than here to come back and show that I can play and be a good player. I'm really excited to show that and happy to be back."
He has 111 points (34 goals, 77 assists) in 446 NHL games with the Blackhawks and Hurricanes, and won the Stanley Cup with Chicago in 2013 and 2015.

Maletta, 23, had four assists in 29 games with Cleveland and Tucson in the American Hockey League last season. He has not played in the NHL.
Campbell, 30, had six points (two goals, four assists) in 60 AHL games with Tucson. He has 42 games of NHL experience, most recently with the Toronto Maple Leafs in 2015-16.
Entwistle, an 18-year-old forward, was selected by the Coyotes in the third round (No. 69) of the 2017 NHL Draft. He had 38 points (13 goals, 25 assists) in 49 games with Hamilton of the Ontario Hockey League.
This is the third time in recent years the Coyotes took on a contract in order to acquire a pick or player. They selected defenseman Jakob Chychrun (No. 16) in the 2016 NHL Draft with the first-round pick acquired along with center Pavel Datsyuk from the Detroit Red Wings on June 24, 2016, and acquired forward Lawson Crouse with forward Dave Bolland from the Florida Panthers on Aug. 25, 2016.
"Cap space is a very valuable asset," Chayka said. "Our ability to use it and leverage it has gotten us players like Jakob Chychrun, Lawson Crouse, and obviously this deal is a big part of that. That was one element of it."
