Abstract
Crystals of the title compound are orthorhombic with a= 7·69, b= 24·42, and c= 7·94 Å, space group Pnma(D2h 16, no. 62). A three-dimensional X-ray analysis of the structure was made with Weissenberg photographic data, estimated visually (783 independent reflections). The structure was solved by conventional Patterson and Fourier methods and refined by block-diagonal least-squares to a final R of 0·069. The [NiN4] co-ordination polyhedron [Ni–N = 1·860(7) and 1·923(7)Å] is essentially planar (Ni atom 0·04 Å out of the symmetry imposed N4 plane), but the molecule has an oblique-puckered conformation, with the aromatic moieties of the ligand inclined at 36·6° to one another, and the chelate ring containing the trimethylene moiety has an uncommon symmetrical ‘boat’ conformation.Keywords
