Crystal and molecular structure of bis-(1-m-tolylazo-2-naphtholato)-nickel(II)

Abstract

The X-ray structural analysis of trans-bis-(1-m-tolylazo-2-naphtholato)nickel(II) has shown that the co-ordination is square-planar, the bonding from the ligand to the metal being through the oxygen atom and the nitrogen atom further from the naphthyl ring. The crystals are monoclinic, P2₁/c, a= 16·532, b= 5·082, c= 19·382 Å, β= 125·04°. Ni–O = 1·85, Ni–N = 1·89 Å.
