SYNTHESIS AND STRUCTURE OF AN NONTRIVIAL COORDINATION POLYMER {[Na2Co(pfb)2(H2O)8](pfb)2}n WITH PENTAFLUOROBENZOATE ANIONS

By the interaction of cobalt(II) chloride, sodium hydroxide, and pentafluorobenzoic acid (Hpfb) in water the first heterometallic complex of cobalt with pfb– anions is obtained. According to the X-ray crystallographic analysis, the complex is a cationic 1D polymer with the general formula {[Na2Co(pfb)2(H2O)8](pfb)2}n.
