Xu, Li published the artcileSupramolecular structure of bis(4-benzoyl-3-methyl-1-phenyl-5-(2H)-2-pyrazolonato)copper(II), COA of Formula: C17H14N2O2, the publication is Asian Journal of Chemistry (2013), 25(13), 7629-7630, database is CAplus.
The mol. of the Cu(II) complex with the empirical formula C34H26N4O4Cu, bis(4-benzoyl-3-methyl-1-phenyl-5(2H)-2-pyrazolonato)copper(II), is rigorously centrosym. [symmetry codes: -x + 1, -y + 1, -z + 1]. Each Cu(II) atom is four-coordinated by two O atoms (O1 and O1#) from pyrazolone ring in deprotonated enol-form and other two O atoms (O2 and O2#) in carbonyl-form forming a rigorously square planar geometry. In the crystal structure, weak intermol. C-H···O H bonds link the title mols. into an infinite 1-dimensional supramol. chains structure.
