Narrative:
The crj was climbing off of slc to FL310. The MD11 was en route eastbound at FL290. I asked the previous controller to stop the crj at FL280 for traffic if he hadn't already shipped him. He nodded to me, so I expected the crj to be stopped at FL280. The previous controller apparently only heard me say 'ship him.

Title: INTRAFAC ZLC CTLR COORD BREAKDOWN RESULTS IN OPERROR BTWN CLBING CRJ AND ENRTE MD11.
Narrative: THE CRJ WAS CLBING OFF OF SLC TO FL310. THE MD11 WAS ENRTE EBOUND AT FL290. I ASKED THE PREVIOUS CTLR TO STOP THE CRJ AT FL280 FOR TFC IF HE HADN'T ALREADY SHIPPED HIM. HE NODDED TO ME, SO I EXPECTED THE CRJ TO BE STOPPED AT FL280. THE PREVIOUS CTLR APPARENTLY ONLY HEARD ME SAY 'SHIP HIM.
