Abstract top

In the title compound, [CdCu2(C12H11N2O5)2(H2O)3]·2H2O, the CuII atoms are in a square plane of N2O2 atoms contributed by the tetradentate Schiff base trianion. The CuII atoms are coordinated by one phenolate O atom, one imine N atom, one amido N atom and one carboxylate O atom. The CdII atom is connected via the carboxylate groups, forming a heterotrinuclear CuII-CdII-CuII system. The CdII atom is seven-coordinate in a pentagonal-bipyramidal geometry with four O atoms from two carboxylate groups and three aqua ligands. The heterotrinuclear molecules are linked to the uncoordinated water molecules by O-H...O hydrogen bonds into a three-dimensional framework.

Comment top

In recent years, the design and synthesis of Schiff base heteronuclear complexes that provide catalyst, biological activity, optical, magnetic materials (Wu et al., 2007; Costes et al., 2006; Liu et al., 2004; Zou et al., 2003; Akine et al., 2008) caused an increasing interest in coordination chemistry. One of the best strategies to design heterometallic species is the 'complex as ligand' approach (Miyasaka et al., 1996). In this article, we present the synthesis and structure of the title heterotrinuclear Schiff base complex derived from 4-methoxy-salicylaldehyde and glycylglycine.

The complex (I) is a asymmetric trinuclear [(CuL)2Cd(H2O)3] unit with the the L3- bound to CuII and CdII atoms and crystallizes in the triclinic space group P1 (Fig. 1). Two [CuL]- groups are connected by CdII cation in cis form to constitute a trinuclear CuII–CdII–CuII unit with Cu···Cu distances of 7.541 Å. [CuL]- anions have approximately square-planar structures. The Schiff base ligand L3- acts as a triple negatively charged quadridentate ONNO chelate and coordinated to the CuII atom via one phenolic oxygen, one imino nitrogen atom, one deprotonated amide nitrogen atom and one carboxylato oxygen atom. The Cu—O and Cu—N bond distances are in the range of 1.882 (2)–1.985 (2) Å and 1.889 (3)–1.923 (3) Å, respectively. The phenyl ring [C(1)—C(6)] / [C(13)—C(18)] and the chelate ring [O(1), C(1), C(6), C(7), N(1), Cu(1)] / [O(6), C(13), C(18), C(19), N(3), Cu(2)] make a small dihedral angle of 7.5 (2) ° / 8.9 (2) °, suggesting a large π-electron delocalization. The chelate rings [O(1), C(1), C(6), C(7), N(1), Cu(1)] and [O(6), C(13), C(18), C(19), N(3), Cu(2)] in the trinuclear moiety is almost parallel, with a small dihedral angle of 3.1 (2)°. The CdII atom is in a distorted pentagonal bipyramid environment, ligated by four carboxylato oxygen atoms (O(3), O(4), O(8), O(9)) arising from two [CuL]- units and three aqua ligands (O(11), O(12), O(13)). The seven Cd—O bonds in the structure are in the range of 2.258 (3) - 2.545 (3) Å. In the crystal structure, the hydrogen bonds (Table 1), O(11)–O(14), O(7)–O(11) and O(7)–O(14) formed a hexagon ring (Fig. 2(a)). The hexagon rings are further connected by CdII ions and hydrogen bonds composing two-dimensional framework in ac-plane. The two-dimensional frameworks are further connected via the intermolecular hydrogen bonds O(12)–O(2), O(12)–O(15) and O(15)–O(9) to constitute a three-dimensional network (Fig. 2(b)).

Experimental top

Glycylglycine (5 mmol), 4-methoxy-salicylaldehyde (5 mmol) and LiOH (10 mmol) were dissolved in MeOH/H2O (30 ml, v:v = 1:1) and refluxed for 30 min. Then Cu(ClO4)2.6H2O (5 mmol) was added to the solution and the resulting solution was adjusted to 9–11 by 5 mol/L NaOH solution. After stirring at room temperature for 1 h, CdCl2.2.5H2O (2.5 mmol) was added. A violet precipitate was obtained immediately. After stirring for another 30 min and then filtrated, the precipitate was recrystallized from water. The violet crystals suitable for X-ray diffraction were obtained after one week. (yield 45% based on Cu(ClO4)2.6H2O).

Refinement top

The water H atoms in (I) were located in a difference Fourier map with a distance restraint of O—H = 0.85 Å and Uiso(H) =1.5Ueq(O). All other H atoms were positioned geometrically and constrained as riding atoms, with C—H distances of 0.93–0.97 Å and Uiso(H) set to 1.2 or 1.5Ueq(C) of the parent atom.

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.
