Abstract
We have designed a bidentate ligand with multi-proton donor property as a building block of models for one-dimensional heterobimetallic complexes. We have synthesized [Cu(bbim)2] (nBu4N)2 (1) as a candidate for the building block of such one-dimensional complexes. The crystal structure analysis of 1 and magnetic characterization by single-crystal ESR spectroscopy have been carried out. The crystal data is as follows: orthorhombic, P2I2I2, a = 17.860 Å, b = 20.274 Å, c = 8.704 Å, Z = 2. ESR measurements of non-magnetically diluted single crystals of 1 have shown that Cu(II) ions are in the tetrahedral ligand field with great tetragonal distortion, being in accord with the molecular structural data on 1 by the X ray analysis.
