 Abstract    von C(NMe2)4 mit Carbonylverbindungen der 6. Gruppe. Kristallstrukturen von [C(NMe2)3][(C0)5CrC(0)NMe2], [C(NMe2)3]2[Mo2(CO)10] und [C(NMe2)3][(CO)4M o(02CNMe2)] Reactions of C(NMe-,)4 with Group 6 Carbonyl Compounds. Crystal Structures of [C(NMe2)3][(C 0)5CrC(0)NMe2], [C(NMe2)3]2 [Mo2(CO)10] and [C(NMe2) 3 ][(CO)4 M o(0 2 CNMe2)] The reaction of C(NMe2)4 (1) with M(CO)6 (M = Cr, W) in THF solution leads to the anionic carbamoyl complexes [C(NMe2)3][(C0)5MC(0)NMe2] (2a, M = Cr; 2c M = W). In the case of M = Mo the resulting complex 2b is not obtained; instead, the salts [C(NMe2)3]2[Mo2(CO)10] (3) and [C(NMe2)3][(CO)4M o(02CNMe2)] (4) are isolated. The crystal structures of 2a, 3, and 4 are presented. In the salt-like compounds no interatomic contacts between anion and cation exist, and the cations are disordered. The structure of 4 shows two independent molecules. The compounds were further characterized by IR and NMR spectroscopy.
