Syntheses and crystal structures of [Ni(IIP)2] and [Cu2(PMP)2(μ1,1-N3)2] · MeOH (IIP = 2-iminomethyl-4,6-diiodophenolate, PMP = 2-[(2-phenylaminoethylimino)methyl]phenolate)

Abstract

A new centrosymmetric mononuclear nickel(II) complex, [Ni(IIP)2] (I), and a new end-on azido-bridged dinuclear copper(II) complex, [Cu2(PMP)2(μ1,1-N3)2] · MeOH (II) (IIP = 2-iminomethyl-4,6-diiodophenolate, PMP = 2-[(2-phenylaminoethylimino)methyl]phenolate), have been prepared from similar tridentate Schiff bases derived from N-phenylethane-1,2-diamine with 3,5-diiodosalicylaldehyde and salicylaldehyde, respectively. The complexes were characterized by elemental analysis, infrared spectra, and single-crystal X-ray diffraction. Complex I crystallizes in the monoclinic space group P21/c with unit cell dimensions a = 4.936(1), b = 11.779(3), c = 15.789(4) A, β = 90.722(3)°, V = 918.0(4) A3, Z = 2, R1 = 0.0267, and wR2 = 0.0546. Complex II crystallizes in the orthorhombic space group Pna21 with unit cell dimensions a = 23.370(2), b = 12.210(1), c = 11.438(1) A, V = 3263.8(5) A3, Z = 4, R1 = 0.0461, and wR2 = 0.0891. The Ni atom in I is in a square planar coordination, and the Cu atoms in II are in square pyramidal coordination.
