Abstract

The synthesis and crystal structure of a new three dimensional cobalt(II) complex [Co(C6H12N4)2(H2O)4Co(H2O)6][SO4]2.6H2O are reported. It crystallizes in the triclinic space group P-1 with a = 13.394(3), b = 16.077(3), c = 9.282(2) Å, α = 89.71(2), β = 90.42(2), γ = 114.02(2)°, V = 1825.6(7)Å3 and Z = 2. The structure is comprised of [Co(C6H12N4)2 (H2O)4Co(H2O)6][SO4]2 units and H2O molecules. Two molecules of ligand and four molecules of water chelate one type of CoII in an octahedral fashion through two N and four O atoms: the four O atoms form the equatorial plane and the two N atoms occupy the apical positions. The other type of CoII cation is chelated by six water molecules.
