Crystal structure of bis­(μ2-4-tert-butyl-2-formyl­phenolato)-1:2κ3O1O2:O1;3:4κ3O1O2:O1-bis­(4-tert-butyl-2-formyl­phenolato)-2κ2O1O2;4κ2O1O2-di-μ3-methoxido-1:2:3κ3O;1:3:4κ3O-di-μ2-methoxido-1:4κ2O;2:3κ2O-tetra­copper(II)

摘要

The structure of the title compound, [Cu4(CH3O)4(C11H13O2)4], consists of dimeric dinuclear copper(II) complexes oriented around a centre of inversion. Within each dinuclear fragment, the two Cu^II atoms are in a distorted square-planar coordination sphere. Two neighbouring fragments are linked by four apical Cu—O contacts, yielding an overall square-pyramidal coordination environment for each of the four Cu^II atoms. The mol­ecules are arranged in layers parallel to (101). Non-classical C—H⋯O hydrogen-bonding inter­actions are observed between the layers.
