Synthesis and crystal structure of a macrocyclic complex precursor:: Bis-(2-amino-1-methyliminobenzene)1,2-ethane nickel(II) dichloride

NiLCl2 (L = bis-(2-amino-1-methyliminobenzene)1,2-ethane) crystallizes in space group P-1 with a = 9.042( 2), b = 10.263(10), c = 11.045(2) angstrom, alpha = 94.76(10), beta = 108.30(10), gamma = 109.86(10)degrees, Z = 2, and represents a precursor of a tetradentate azamacrocyclic complex. The structure is stabilized by a system of intramolecular and intermolecular H-bonding involving chloride ions and nitrogen atoms. The coordination geometry about nickel(II) is slightly distorted octahedral.
