A two-dimensional network of R(2)(2)(16) and R(4)(2)(8) rings in trans-bis(4-aminopyridine-kappaN(1))bis(benzoato-kappa(2)O,O')copper(II) benzene 0.75-solvate

Abstract

The structure of the title supramolecular complex, [Cu(C(7)H(5)O(2))(2)(C(5)H(6)N(2))(2)].0.75C(6)H(6), has been determined. The Cu(2+) ion lies on an inversion centre and is coordinated by four O atoms of two opposing benzoate molecules and two pyridine N atoms of two opposing aminopyridine molecules. The partially occupied benzene site lies across a twofold rotation axis. The crystal structure is dominated by two-dimensional networks containing two different hydrogen-bonded rings [R(2)(2)(16) and R(4)(2)(8)].
