Unique example of a trigonal dodecahedral Na+ in a compartmental Schiff base N,N′-(1,2-Phenylene)-bis(3-methoxysalicylideneimine)

A unique heteronuclear Schiff base compound, [(NiL)Na(NiL)]ClO4 (1), derived from the compartmental Schiff base ligand N.N'-(1,2-Phenylene)-bis(3-methoxysalicylideneimine) (H2L) has been prepared and its molecular structure has been elucidated on the basis of X-ray crystallography. The compound contains an octa-coordinated Na+ in trigonal dodecahedral geometry and two terminal square planar Ni(II). (C) 2011 Elsevier B.V. All rights reserved.
