Zur Reaktion von [η5-CpMCl4] (M = Nb, Ta) mit E(SiMe3)2 (E = S, Se). Die Kristallstrukturen von [Cp8Ta6S10], [Cp3Ta3S7Cl2], [Cp4Ta4S13] und [Cp3Nb3Se5Cl2]
Reaction of [η5-CpMCl4] (M = Nb, Ta) with E(SiMe3)2 (E = S, Se). The crystal structures of [Cp8Ta6S10][TaSCl5], [Cp3Ta3S7Cl2], [Cp4Ta4S13] and [Cp3Nb3Se5Cl2]
- [η5-CpMCl4] (M = Nb, Ta) reacts with E(SiMe3)2 (E = S, Se) to form different multinuclear clusters. The cation [Cp8Ta6S10]2+ (1) consists of a planar Ta2S2-ring of which each Ta is coordi-nated to two Cp2TaS2-fragments. [Cp4Ta4S13] (3) can be derived from [Cp3Ta3S7Cl2] (2) by addition of a CpTaS6-unit to a triangle of Ta-atoms bridged by S- and S2-ligands. The niobium atoms in [Cp3Nb3Se5Cl2] (4) arrange in a chain structure with Nb coordination numbers varying from 4-6.
