Synthesis, X-ray phase analysis (XRPA), and IR spectroscopic study were performed to investigate the structure of [Cu( m-HBH)2(OH2)2]SO4·H2O, where m-HBH = C7H8O2N2 (3-hydroxybenzoylhydrazine); a = 7.154(3) â„«, b = 8.012(2) â„«, c = 20.061(2) â„«, β = 90.56(2)°; P21, Z = 2, R( F) = 0.046. The structure of the compound consists of the [Cu( m-HBH)2(OH2)2]²⁺ complex cations, SO anions, and one water molecule. The copper atom is surrounded by a tetragonal bipyramid; c.n. is 6 = 4 + 2 (the distances are 2.030(5) â„«, 2.054(6) â„«, 2.061(5) â„«, and 2.097(3) â„« (equatorial); 2.459(4) â„« and 2.53(4) â„« (axial)). In complex compounds of 3 d metals containing m-HBH, the function of the latter is probably invariable; the distribution of the anions and water molecules in the structure depends on the type of the metal and on the anion shape and geometry for metals with slightly different ionic radii.
