Synthesis, Characterization, and Crystal Structure of a Dicyanamide-Bridged Polymeric Nickel(II) Complex With 4-Chloro-2-[(3-dimethylaminopropylimino)methyl]phenol

Abstract

A dicyanamide-bridged polymeric nickel(II) complex, [NiL(MeOH)(μ₂-N(CN)₂)]_n, where L is the anionic form of the Schiff base 4-chloro-2-[(3-dimethylaminopropylimino)methyl] phenol, was synthesized and characterized by elemental analysis, IR spectrum, and single-crystal X-ray diffraction. The crystal of the complex crystallizes in the monoclinic space group P2₁/c, with unit cell dimensions a = 9.860(1) Å, b = 20.234(2) Å, c = 18.601(2) Å, β = 103.127(2)°, V = 3614.0(6) ų, Z = 4, R ₁ = 0.0368, wR ₂ = 0.0702. The Ni atom of the complex is in an octahedral coordination, with two N atoms of the Schiff base ligand, one methanol O atom, and one teminal N atom of the dicynamide ligand defining the equatorial plane, and with one phenolate O atom of the Schiff base ligand, and one terminal N atom of another dicyanate ligand occupying the two axial positions.
