UO2[RC(C4H2N)2]2(L) (L = THF (4R-THF); DMAP (4R-DMAP)) (R = tolyl, p-OMe-C6H4, mesityl, ferrocenyl). The THF adducts, 4R-THF, are unstable in aromatic and nonpolar solvents and rapidly decompose to 2 and an intractable uranium-containing solid. On the other hand, the DMAP adducts, 4R-DMAP, are indefinitely stable in solution. The solid-state structures of 4R-THF and 4R-DMAP reveal distorted trigonal bipyramidal
