Abstract top

In the title compound, [Cd(C2H4O2)(C12H8N2)2]ClO4·H2O, the CuII ion is in a distorted octahedral coordination geometry with normal Cd-O and Cd-N bond lengths. The cation and anion both lie on crystallographic twofold axes. In the crystal structure, intermolecular O-H...O hydrogen bonds form one-dimensional chains along [100] and in addition weak [pi]-[pi] stacking interactions connect molecules along [001]. The Cg1 (central fused benzene ring) and Cg2 (outer fused pyridine ring) centroid-centroid and perpendicular distances are 3.746 (2) and 3.623 (2) Å, respectively, with Cg1...Cg2i = 3.602 (2) Å [symmety code: (i) -x, 1 - y, 1 - z].

Comment top

The formula unit of (I) comprises a monnuclear [Cd(phen)2(CH 3COO)]+ cation (Fig. 1), a perchlorate anion and a hydrate. The Cd II ion is in a distorted octahedral CdN4O2 geometry coordinated by four N atoms of phen ligands and two O atoms of a chelating bidentate acetato anion. By virtue of the twofold symmetry, atoms C13, C14, O1, O1b atoms are exactly planar (Zhang et al., 2003)[symmety code: (b) -x, y, 1/2 - z]. In the crystal structure, one-dimensional chains along [100] are formed by intermolecular Owater—H···Operchlorate and Owater –H···Owater hydrogen bonds (Fig. 2. and Table 2). In addition weak π-π stacking interactions form chains along [001] as shown in Fig.3. Cg1 and Cg2 are the centroids defined by atoms C4/C5/C6/C7/C11/C12 and N2/C7/C8/C9/C10/C11, respectively. The relevant centroid–centroid and perpendicular distances defining these interactions are 3.746 (2), and 3.623 and 3.602 Å for Cg1··· Cg2i [symmety code:(i) -x,1 - y,1 - z].

Experimental top

Cd(CH3COO)2 ˙ 2(H2 O)(0.266 g, 1 mmol), NaClO4 (0.14 g, 1 mmol) phen (0.396 g, 2 mmol) were dissolved in a water-methanol solution (40 ml, 1:1). The mixture was refluxed for 4 h, and then filtered after cooling to room temperature. Single crystals of (I) were obtained after two weeks.

Refinement top

H atoms bonded to O atoms were located in difference maps and then included in the refinement with bond-length restraints of O – H = 0.82 (2) Å, with Uiso (H) = 1.5Ueq (O). H atoms bonded to C atoms were placed in calculated positions and included in the riding-model approximation, with C–H = 0.93—0.96 Å and U iso(H) = 1.2U eq (C of aromatic) or 1.5U eq(C of methyl). Atoms O2/O3/O4 of the perchlorate anion are disordered over a twofold axis with equal occupancies. The largest peak of 1.18 Å-3 in the final differnce Fourier is close to atom Cl1.

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.
