Synthesis, crystal structures and magnetic properties of helical double-stranded three-dimensional network [Co(NO3)2(bpt)2·2CH3OH]n and two-dimensional network [Mn(NCS)2(bpt)3·H2O]n (bpt=N,N′-bis(3-pyridylmethyl)thiourea)

Compounds [Co(No-3)(2)(bpt)(2).2CH(3)OH](n) (1) and [Mn(NCS)(2)(bpt)(3).H2O](n) (2) (bpt = N,N'-bis(3-pyridylmethyl)thiourea) have been synthesized and characterized structurally. Two bpt ligands coordinate simultaneously to two cobalt(II) centers to generate the double helical one-dimensional chain [Co(NO3)(2)(bpt)(2)](n). Intermolecular hydrogen-bonding arising from the interaction of thiourea units of bpt with NO3- ions or solvent molecular forms a three-dimensional supramolecule in the solid structure (polymer 1). Bpt ligands (polymer 2) acting as bridges connect to two manganese(II) centers lead to the one-dimensional linear chain [Mn(NCS)(2)(bpt)(3)](n). The two-dimensional network was formed by O...H-N, S...H-O and OH...SCN hydrogen bonds. The determination of variable-temperature magnetic susceptibilities (5-300 K) of the two compounds shows that the magnetic behavior obeys the Curie-Weiss law.
