- Department of Chemistry, Gulbarga University, Gulbarga-585 106 Manuscript received 25 October 1983, revised 16 April 1984, accepted 11 September 1985 Complexes of CoII, NiII, CuII, ZnII, CdII and HgII metal ions with 3,4-dihydro-4- oxobenzofuro[3,2-d]pyrimidine(L) have been synthesised. Their structural features have been investigated on the basis of elemental analyses, electronic and infrared spectral data. The ligand field parameters Dq, B' and β are calculated for CoII, NilI and Cull complexes. The it spectra of the complexes reveal both bidentate and mono-dentate nature of the ligand. The insolubility in common organic solvents and electronic spectra suggest the polymeric octahedral geometry for NiII, and distorted octahedral structure for CoII and CuIl complexes. An octahedral polymeric structure may be proposed for ZnII, CdII and HgII complexes.
