Adelaide and Geelong complete a deal that sends Patrick Dangerfield to Geelong in exchange for picks 9 and 28 in the 2016 national draft as well as young midfielder Dean Gore.
In addition, the Cats also gain Adelaide's third-round draft pick, currently No.50.
Crows head of football David Noble said the trade provided more compensation than would have been available under free agency rules, which he said left affected clubs with little room to move.
"All along we were intent on doing what was in the best interests of our club, and we have been able to deliver the best possible outcome," Noble said.
"I would also like to acknowledge Geelong for the professional manner in which these negotiations were handled."
