While working the radar at the Center; I verbally coordinated with the controller next to me that I would coordinate with Approach; that Approach can have control for descent on Aircraft X who is landing at an airport just outside of their airspace. I called Approach and told them Aircraft X will be descending to 9;000 feet; their control with me. As Aircraft X started to descend; Aircraft Y; a C525; departed southwest bound climbing to 10;000 feet from another Approach's airspace that would put him in conflict with Aircraft X. I then called them and told them to stop Aircraft Y at 8;000 feet and assign a 180 heading; to go behind Aircraft X and to avoid the TFR area. I then called the other Approach and pointed out Aircraft Y climbing to 8;000 feet on a 180 heading and that Aircraft X is still their control reference that traffic; and my control on Aircraft Y. They said point out approved. As Aircraft Y leveled off at 8;000 [feet]; Aircraft X continued his descent through his altitude. Approach then turned Aircraft Y further southeast bound to avoid conflict with Aircraft X in the descent. With the approved coordination with both Approach Controls; I'm unsure of what form of separation was being applied or if all of the approved coordination was accurately relayed to the appropriate controller.
A Center Controller reported they handed off an arriving aircraft to an Approach Control and coordinated a plan to resolve a confliction with a departure from another Approach Control but observed the arriving aircraft descend through the altitude of the departing aircraft.
