Abstract: | Summary Analytical data, room temperature magnetic moment values, electronic and i.r. spectral measurements down to 200 cm–1 on the coordination compounds formed by the interaction of cobalt(II) chloride, bromide, thiocyanate, acetate and nitrate with 4,4 -bipyridyl and 4,4 -bipyridylN,N -dioxide indicate that the isolated compounds are coordination polymers having tetrahedral or octahedral stereochemistry around cobalt(II) involving bridging 4,4 -bipyridyl/4,4 -bipyridylN,N -dioxide molecules. Terminally bonded acetato- and nitrato-ligands and bridging or terminally bonded chloro-, bromo- and thiocyanato-groups in the solid state. |
