Abstract
The reaction of CoX2 (X = Br, Cl) and pyrimidine (PM) in H2O gave crys tals of CoPM2X2. The crystal structure analysis revealed a chiral thre e-dimensional network of the Co(II) ions. Weak ferromagnetism with rel atively large spontaneous magnetization was observed below 5 K for bot h compounds.
