{4,4′-Dibromo-2,2′-[2,2-dimethylpropane-1,3-diylbis(nitrilomethylidyne)]diphenolato-κ(4) O,N,N′,O′}copper(II)
In the title compound, [Cu(C(19)H(18)Br(2)N(2)O(2))], the Cu(II) ion is in a tetrahedrally distorted planar geometry, involving two N and two O atoms from the tetradentate Schiff base ligand. Intermolecular C—H⋯O hydrogen bonds form an eight-membered R (2) (2)(8) motif. The dihedral angle betwen...

Sumario: | In the title compound, [Cu(C(19)H(18)Br(2)N(2)O(2))], the Cu(II) ion is in a tetrahedrally distorted planar geometry, involving two N and two O atoms from the tetradentate Schiff base ligand. Intermolecular C—H⋯O hydrogen bonds form an eight-membered R (2) (2)(8) motif. The dihedral angle betwen two benzene rings is 36.34 (9)°. There are intermolecular Cu⋯Br [3.4566 (5) Å] and Cu⋯·N [3.569 (3) Å] contacts, which are significantly shorter than the sum of van der Waals radii of the relevant atoms. These interactions, along with the intermolecular C—H⋯π and π–π [centroid–centroid distances of 3.709 (1) and 3.968 (2) Å] interactions, link neighbouring molecules into a one-dimensional infinite chain along the c axis. |
