Abstract

The title compound crystallizes in space groupP21/n witha=10.651(3),b=11.082(2),c=8.993(3) Å,β=106.79(3)°;R=0.064 andR w=0.074 for 3399 observed reflections (I≥3σ(I)) from 3674 measured. The structure was solved by direct methods and refined by least squares. The Ni atom of the complex is located at a center of inversion, and is surrounded by four nitrogen atoms of the two ligands in square-planar geometry. The oxygen atoms of the two centrosymmetrically related water molecules complete the coordination around the metal ion to form an elongated octahedron.
