Co-ordination compounds of cobalt (II) with some N-substituted ureas

The preparation of a series of new complexes of cobalt(II) containing N-substituted ureas is reported. Octahedral [CoL6]X2 (X NO3, Cl, Br, 1 2SO4) and mixed octahedral-tetrahedral [CoL6][CoX4] (X Cl, Br) complexes were obtained. The formation of solid tetrahedral [CoL2X2] (X Cl, Br) complexes is als...
