(-3,4-Diacetylhexa-2,4-diene-2,5-diolato-⁴O²,O³:O⁴,O⁵)bis[aqua(1,10-phenanthroline-²N,N')copper(II)] bis(tetrafluoridoborate) monohydrate

Abstract: In the title compound, [Cu₂(C₁₀H₁₂O₄)(C₁₂H₈N₂)₂(H₂O)₂](BF₄)₂·H₂O, the two Cu atoms are each chelated by the acetylacetonate unit of the 3,4-diacetylhexa-2,4-diene-2,5-diolate (tae) ligand. The Cu atoms are square-pyramidally pentacoordinated, with one bidentate 1,10-phenanthroline (phen) and the tae ligand basal and one water molecule apical. The pyridyl rings of the phen ligands participate in - [centroid-centroid distance = 3.894 (3) Å] and C-H interactions, generating layers which are interconnected through O-HO and O-HF hydrogen bonds between the water molecules and the tetrafluoridoborate anions. The F atoms of both tetrafluoridoborate anions are each disordered over two positions of equal occupancy.
