Di-μ-hydroxido-bis-[hemiaqua-(N,N,N′,N′-tetra-methyl-ethane-1,2-diamine)-copper(II)] bis-(tetra-fluoridoborate)

摘要

The title compound, [Cu2(OH)2(C6H16N2)2(H2O)](BF4)2, consists of dinuclear centrosymmetric [Cu2(OH)2(tmen)2(H2O)]2+ complex cations (tmen = N,N,N′,N′-tetra-methyl-ethane-1,2-diamine) and tetra-fluoridoborate anions. In the cation, the CuII atom shows a slightly distorted square-pyramidal coordination geometry provided by a pair of μ-OH? anions and by the N atoms of a chelate tmen ligand in the basal plane. The apical position is statistically occupied by the O atom of a half-occupancy water mol-ecule. The F atoms of the anion are disordered over three sets of sites with occupancies of 0.598?(9):0.269?(6):0.134?(8). The crystal packing is governed by ionic forces as well as by O—H?F hydrogen bonds.
