trans-Tetraaquabis(1,3-di-4-pyridylpropane-N)cobalt(II) naphthalene-1,5-disulfonate monohydrate

K.-F. Han, H.-Y. Chen and Z.-M. Wang

Abstract: In the title compound, [Co(C₁₃H₁₄N₂)₂(H₂O)₄](C₁₀H₆O₆S₂)·H₂O, the Co^II ion, which lies on a centre of symmetry, is coordinated by two N atoms from two 1,3-di-4-pyridylpropane (dpp) ligands and four aqua O atoms in a distorted octahedral geometry. Two C atoms of the flexible -CH₂CH₂CH₂- spacer in the dpp ligand are disordered over two positions. The 1,5-naphthalenedisulfonate dianion, which lies about an inversion centre, does not coordinate to the Co^II ion but balances the charge. The cations, anions and water molecules are connected by a three-dimensional hydrogen-bonding network.
