Bis(salicylhydrazide-[kappa]2N,O)sulfatozinc(II) monohydrate

W. Luo, X.-G. Meng, X. Li, G.-Z. Cheng and Z.-P. Ji

Abstract top

The title complex, [Zn(SO4)(C7H8N2O2)2]·H2O, contains neutral molecules of a mononuclear ZnII complex, in which the salicylhydrazide ligand is N,O-chelated to the ZnII ion. The ZnII ion is coordinated, in a tetragonal-pyramidal environment, by two O atoms and two N atoms from two salicylhydrazide ligands forming a basal plane, and one O atom from the sulfate anion occupying the apical position. The water molecule is disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.

Comment top

The molecular self-assembly of supramolecular architectures has received much attention during recent decades (Tao et al., 2000). The structures and properties of such systems depend on the coordination and geometric preferences of both the central metal ions and the bridging building blocks, as well as on the influence of weaker non-covalent interactions, such as hydrogen bonds and π-π stacking interactions. In this paper, we report the synthesis and crystal structure of the title compound, (I), [ZnSO4(C7H8N2O2)2]·H2O, (Fig.1) a novel ZnII complex formed by the ligand salicylhydrazide. The ZnII ion is situated in a tetragonal-pyramidal enviroment consisting of two O atoms and two N atoms from two ligands in the basal plane,and an O atom from the sulfate anion in the apical position. Intermolecular O—H···O hydrogen bonds (Table 1) result in a two-dimensional network.

Experimental top

Salicylhydrazide (15.2 mg, 0.1 mmol) was dissolved in a mixed solvent (20 ml) of DMF and methanol (1:1), then ZnSO4·7H2O (28.7 mg, 0.1 mmol) was added, stired for 10 min and filtered. Colourless single crystals suitable for X-ray diffraction analysis were obtained by slow diffusion of the filtrate for one week,.

Refinement top

Except the water H atoms, all the H atoms were located at the ideal positions with C–H = 0.93 Å (aromatic), N–H = 0.86 Å (imine) and 0.90 Å (amine), O–H = 0.82 Å(phenol); and Uiso(H) = 1.2Ueq(C) for aromatic H atoms, Uiso(H) = 1.2Ueq(N) for H atoms bonded to N atoms and Uiso(H) = 1.2Ueq(O) for hydroxyl H atoms. The water H atoms were located from the difference maps and refined with the constraints of O–H = 0.82 (1) Å, H–H = 1.35 (1) Å, and the Uiso values of these two H atoms were set 1.5 times of Ueq value of water O9 atom. The water O atom was disordered over two positions with occupancies of 0.589 (3):0.411 (3).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
