The closest, I think, might be a Warlock character. There are powers and builds that can get a lot of Necrotic damage (read: Negative energy), and the Dark pact particularly offers chances for doing damage to yourself or your allies for the chance to do greater damage to your enemies.
Aside from that, Melblen may let you swap keywords on some powers for a particular class, say changing Radiant damage to Necrotic on a Cleric, as that sort of houseruling is fairly easy in 4E. More likely though, you'll want to check out classes with powers that incapacitate or charm/dominate. Plenty of Leader classes and Controller classes can do that. I once had a player running a Psion that would rely a lot on forcing enemies to hit each other, take big penalties to attacks, etc. Powers that Dominate targets tend to be higher level ones, but they're there.
