Triaqua(N²,N⁴-di-2-pyridylpyrimidine-2,4-diamine)cobalt(II) fumarate

M. Yang

Abstract: The Co atom in the title compound, [Co(C₁₄H₁₂N₆)(H₂O)₃]C₄H₂O₄, has a mer-CoN₃O₃ octahedral coordination arising from the tridentate N²,N⁴-di-2-pyridylpyrimidine-2,4-diamine (tpda) ligand and three coordinated water molecules. The asymmetric unit contains two fumarate half-anions, both completed by inversion symmetry. A network of N-HO and O-HO hydrogen bonds leads to a three-dimensional network in the crystal structure.
