Abstract
Coordination compounds have been prepared from 4,4′-hipyridylN,N′-dioxide (4,4′-BipyO2) and some hivalent metal halides, nitrates and thiocyanates as well as silver(1) nitrate.viz., Co(4.4′-BipyO2)2Cl2, Co(4.4′-BipyO2)Br2, Co(4,4′-Bi-pyO2)(NO3)2. Co(4,4′-BipyO2)2(NCS)2. Ni(4.4′-BipyO2)2Cl2. Ni(4,4′-BipyO2)(NO3)2, Ni2(4.4′-BipyO2)3(NSC)4. Cu(4,4′-BipyO2)(NO3)2. Zn(4,4′-BipyO2(NO3)2, Zn,(4.4′-BipyO2)3-(NCS)4. Cd(4.4′-BipyO2)(NO3)2, Cd(4.4′-BipyO2)2(NCS)2 and Ag(4,4′-BipyO2)(NO3). The products were characterized by magnetic susceptibility. electronic and i.r. spectral measurements down to 200 cm−1. Tentative stereochemistries for the complexes isolated in the solid state are proposed. The ligand field parameters 111 Dy. B. j3. )., and calculated for the cobalt. nickel and copper complexes are consistent with these stereochemistries.
