Abstract

Complex (1), [Et4N]2[(Bp′)CuMoS4Cu2 (μ-Bp′)2Cu2MoS4Cu(Bp′)], was synthesised in acetone by substituting Cl- ligands of [MoS4(CuCl)3]2- by bidentate Bp′ ligands. It crystallises as a centrosymmetric dimeric anion, containing MoS4/2- and Bp′ units coordinated to Cu(I) atoms to form a novel structure. Bis(pyrazolyl)borate ligands are both bridging and terminal chelating. The copper(I) atoms have two different geometries: 3-coordinate by two S of thiomolybdate and one N of bridging Bp′, and 4-coordinate by two S of thiomolybdate and two N of terminal Bp′. An acetonitrile solution of complex (1) is unstable in air and deposits crystals of (2), [(Bp′)2Cu]. In complex (2), the Cu(II) atom resides on an inversion centre with square planar co-ordination. The crystal structure and molecular geometry of (2) are similar to those of its fluorinated analogue [H2B(3,5- (CF3)2Pz)2]2Cu. © 2001 Elsevier Science B.V.
