Diaquabis(1,10-phenanthroline-²N,N')zinc(II) 2-hydroxy-5-sulfonatobenzoate tetrahydrate

K.-L. Zhang, B. Yang and S. W. Ng

Abstract: The water-coordinated metal centre in the title salt, [Zn(C₁₂H₈N₂)₂(H₂O)₂]C₇H₄O₆S·4H₂O, is chelated by the two bidentate N-heterocycles, leading to an overall distorted octahedral environment. The cation, dianion and solvent water molecules interact by O-HO hydrogen bonds to form a layer motif. The SO₃ group is disordered over two positions with respect to the O atoms in a 0.76 (1):0.24 (1) ratio. One of the solvent water molecules is also disordered over two positions in a 0.56 (4):0.44 (4) ratio.
