Abstract

[MC1 2 (PR 3 ) 2 ] (M = Ni, Pd) reacts with E(SiMe 3 ) 2 (E = S, Se) to form triangular clusters, [Ni 3 S 2 Cl 2 (PPh 3 ) 4 ] (1), [Pd 3 S 2 Cl 2 (PPh 3 ) 4 ] (2), [Ni 3 Se 2 (SeSiMe 3 ) 2 (P(C 2 H 4 Ph) 3 ) 4 ] (4) and [Pd 3 Se 2 (SeSiMe 3 ) 2 (PPh 3 ) 4 ] (3). 1-4 have been characterized by X-ray crystal structure analysis. All these compounds contain a triangular M 3 -core, which is capped by two μ 3 -E-ligands (E = S in 1, Se in 3 and 4).
