Abstract
Heating a solution of cadmium nitrate and isonicotinic acid in N,N'-dimethylformamide or dimethyl sulfoxide gave three new coordination polymers, [Cd(Inic)(2)] center dot 0.5DMF (I), [Cd-3(DMSO)(6)(Inic)(2)(SO4)(2)] (II), and [{Cd(DMSO)(Inic)}(2)(SO4)] center dot 2H(2)O (III), which were studied by X-ray crystallography. Compounds I and III were characterized by IR spectroscopy and elemental and thermogravimetric analyses and luminescence spectroscopy.
