Abstract

Bis(diphenylphosphino)methane copper(I) tetrahydroborate was synthesized by ligands exchange in bis(triphenylphosphine) copper(I) tetrahydroborate, and characterized by XRD, FTIR, NMR spectroscopy. According to XRD the title compound has dimeric structure, [(μ2-dppm)2Cu2(η2-BH4)2], and crystallizes as CH2Cl2 solvate in two polymorphic forms (orthorhombic, 1, and monoclinic, 2) The details of molecular geometry and the crystal-packing pattern in polymorphs were studied. The rare Twisted Boat-Boat conformation of the core Cu2P4C2 cycle in 1 is found being more stable than Boat-Boat conformation in 2.

Abstract

The spectroscopic and theoretical evidence for the intermolecular hydrogen bond with neutral hydride complex as an acid is presented, where CpM-(CO)(sub 3)H hydride complexes (M = Mo, W) are chosen as they are less acidic than HCo(CO)(sub 4). Intermolecular dihydrogen bond (H...H) is found between two neutral hydride complexes using H3BNEt3 as a base.
