 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.

 Title    [Fe(C0)  
 Abstract    4 C(0)NMe 2 ][C(NMe 2)3]; die erste Strukturbestimmung einer Organometallverbindung mit dem Carbeniumion [C(NMe 2) 3 ] + [Fe(C0) 4 C(0)NMe 2 ][C(NMe 2) 3 ]; the First Structure Determination on an Organometallic Compound with the Carbenium Ion [C(NMe 2) 3 ] + The crystal structure of the carbamoyl complex [(C0) 4 FeC(0)NMe 2 ][C(NMe 2) 3 ] (1) is de-scribed. It crystallizes in the triclinic space group PI (a = 7.876(3), b = 10.098(3), c = 12.067(5)Ä, a = 94.25(3), ß = 90.94(3), y = 97.30(3)°, Z = 2) and consists of independent ions. The cation has a planar CN 3 array with sp 2 hybridized C and N atoms. The carbamoyl group of the anion occupies an axial position in the trigonal bipyramidal environment of the iron atom.
