Here's the full deal from Howard Beck:
Knicks trades are complete. It's a 3-team deal w/Dallas and Washington. NY sends Turiaf, 2013 2nd-rd pick and cash to Wizards.
Knicks acquire Chandler, plus rights to Ahmad Nivins and Giorgos Printezis. Mavs get Andy Rautins and protected 2012 2nd-rd pick from Wiz
(And Chauncey Billups is amnestied).
Incidentally, Nivins is a St. Joe's big man who was drafted in '09 and has been playing in Spain ever since. Printezis is Greek and was picked by the Spurs in '07, but stayed in Europe. His nickname is apparently "The Big Fish". He is now officially my favorite Knick of all time.
I'll update with links to stuff from the press conference itself once it's available.
