Crystal and molecular structure of dinitrato-(NNN′N′-tetramethyl-o-phenylenediamine)nickel(II)

Abstract

The structure of dinitrato-(NNN′N′-tetramethyl-o-phenylenediamine)nickel(II) has been determined by three-dimensional single-crystal X-ray methods and has been refined to R 6·9% for 882 independent reflections. The complex crystallizes in the monoclinic space group C2/c with a= 13·80, b= 10·09, c= 10·33 Å, β= 94° 30′, and Z= 4. The molecule has C₂ symmetry: the nickel atom is in a distorted octahedral co-ordination. Spectroscopic measurements have also been made and the results are discussed in the light of the X-ray determination.
