Syntheses And Crystal Structures Of Cobalt(Ii) Chloride Complexes Of 1,3-Bis(Pyridyl-4-Ylthio)Propan-2-One

Reactions of 1,3-bis(pyridyl-4-ylthio)propan-2-one L and CoCl(2)(.)6H(2)O under different conditions gave two new cobalt(II)-chloride-L complexes with distinct structures. Complex [Co(L)(2)Cl-2](.)0.5CH(3)OH}n 1 prepared by solvothermal treatment is a 3D network, whereas complex [Co-3(L)(2)Cl-6(DMF)4](.)2CH(3)OH(.)H(2)O} 2 obtained in DMF-diethyl ether system is a discrete acyclic trimer.
