Synthesis and crystal structure of bis(2-iminopent-2-en-4-onato)nickel(II)

Synthesis and crystal and molecular structure of the title compound have be en performed. It crystallizes in the space group Ccca with 12 molecules in the unit cell. There are two crystallographically independent molecules loc ated on special positions with symmetry 2 or 222. Each molecule is disorder ed over two sires. The Ni2+ ion, chelated by two 2-iminopent-2-en-4-onate a nions, exhibits a planar square coordination. The neighbouring molecules ar e connected by pairs of N-H ... O hydrogen bonds forming a ribbon motif. Is ostructurality of the crystal studied with 2,4-pentadionato-Li complex is d iscussed.
