In the title compound, [Na(H2O)2]ClO4·[Cu2(C9H7NO3)2(C6H7N)2], the CuII atom is coordinated by one N atom and two O atoms from a tridentate N-salicylideneglycinate Schiff base dianion and one N atom from a 3-methyl­pyridine ligand. Longer Cu⋯O contacts [2.680 (2) Å] complete an approximate square-based pyramidal coordination geometry around CuII, forming a dimeric complex across a centre of inversion. The dimeric complexes form stacks along the a axis, with Cu⋯O contacts of 3.332 (2) Å between them. The Na+ cations and perchlorate anions lie on twofold rotation axes between the stacks. The former are coordinated by two disordered water mol­ecules (each with half-occupancy), and form Na⋯O contacts of 3.698 (3) Å to the perchlorate anions and Na⋯π contacts to neighbouring salicylideneglycinate ligands [shortest Na⋯C = 3.516 (3) Å].

Comment top

Copper(II) complexes with tridentate Schiff-base dianions of the N-salicylideneaminoacidato type (TSB2-) have been reported recently (1998ad). These complexes are pyridine adducts. In this paper, we present the structure of the related title compound.

The CuII atom is coordinated by the tridentate N-salicylideneglycinato dianion and the 2-methylpyridine ligand in an approximately square-planar geometry. The pyridine ring is inclined with respect to the mean plane (through O1, O2, N1 and N2) at an angle of 11.5 (2) ° and the CuII atom lies 0.042 (1) Å out of this plane. The Cu—N and Cu—O bond distances [Cu—N 1.919 (2) and 2.018 (2) Å; Cu—O 1.922 (2) and 1.966 (2) Å] do not differ significantly when compared to the 2-ethylpyridine compound (Warda, 1998c). These units are associated into dimers through Cu···O interactions (2.680 (2) Å), and these dimers are associated into stacks along the a axis of the monoclinic unit cell by longer Cu···O contacts (3.332 (2) Å) (Fig. 2). The Na+ cations and perchlorate anions lie between stacks, both on 2-fold axes, forming Na···O contacts of 3.698 (2) Å. The Na+ cation is also coordinated by two water molecules in a bent geometry.

Experimental top

The title compound was synthesized from aqua(N-salicylideneglycinato)copper(II) hemihydrate according to the methods of Ueki et al. (1967) and Warda (1994), with 3-methylpyridine and sodium perchlorate in a 4:3 ethanol-water mixture at room temperature. Dark-green prismatic crystals grew within a few days.

Refinement top

H atoms bonded to C atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.93–0.97 Å and Uiso(H) = 1.2 or 1.5Ueq(C). The H atoms of the water molecules were placed in approximate positions and allowed to ride with O—H = 0.85 Å, Uiso(H) = 1.2 Ueq(O).

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.
