2-Chlorobenzoate Complex of Cu(II): Unexpected Appearance of Halogen···Halogen Contacts in Solid State

Abstract

Complex of copper [Cu2(2-ClBenz)4((acetone)2] (2-ClBenz = 2-chlorobenzoate) was prepared and characterized by X-ray diffractometry. In the crystal structure, the binuclear complex fragments are connected via Cl···Cl contacts (3.440 Å); their energies were estimated by theoretical methods.
