摘要：

Synthesis and structural characterization of new Cu(II) and Ni(II) complexes of (9'-fluorene)-spiro-5-dithiohydantoin are reported. All compounds were studied by means of experimental (C-13 CPMAS NMR, EPR. IR) and quantum-chemical (DFT/B3LYP-6-31G(d,p)) methods. Based on the experimental data, supported by theoretical calculation, the most probable structure of the complexes is suggested. The paramagnetic Cu(II) complex has distorted tetrahedral structure with two water and two ligand molecules coordinated to the metal ion. For the Ni(II) complex square planar geometry is suggested with two ligand molecules coordinated in a bidentate fashion. (C) 2008 Elsevier B.V. All rights reserved.
