Abstract

X-Band e.s.r. spectra of two [Nb(η-C5H5)2{S2P(OR)2}]+ complexes (R = C2H5 or i-C3H7) have been recorded at room temperature and 77 K. They show interaction of the unpaired electron with the 93Nb and the 31P nuclei. A detailed analysis of spin-Hamiltonian parameters is given and the bonding is discussed assuming that the ligand field around niobium has C2v symmetry. The strong and almost isotropic superhyperfine coupling of the unpaired electron with the 31P nucleus is interpretable in terms of delocalization through the sulphur atoms.
