Di-μ-hydroxido-bis­hemiaqua­(NNN′N′-tetra­methyl­ethane-12-diamine)­copper(II) bis­(tetra­fluoridoborate)

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′-tetra­methyl­ethane-1,2-diamine) and tetra­fluoridoborate anions. In the cation, the Cu^II 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 mol­ecule. 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.
