Synthesis and crystal structure of a distorted face sharing double cubane like tetranuclear NiII-Cu2II-NiII compound derived from a reduced di-Schiff base ligand

Abstract

One new tetranuclear face sharing distorted double cubane like hetero-metallic Ni^II₂Cu₂^II compound has been synthesized using a [NiL^R] “metalloligand”, where H₂L^R = N,N'-bis(2-hydroxybenzyl)-1,3-propanediamine. The compound has been characterized by elemental analysis, spectroscopic methods and single crystal XRD. In the compound, in addition to the m₂-phenoxido bridges, the two terminal Ni^II atoms are linked to each of the central Cu^II ion by means of an end-on bridging azido (m_1,1-N₃) ion separately, resulting a tetranuclear cubane like structure.
