S1. Comment

Polynuclear complexes play an important role in the development of coordination chemistry related to magnetism and molecular architectures (Eshel et al., 2000; Jiang et al., 2005; Escuer et al., 2000; El-Behairy et al., 1997; Manhas et al., 2005). The prime strategy for designing these molecular materials is to use suitable bridging ligands that determine the nature of the magnetic interactions (Salem, 2005; Dohlakiya & Patel, 2005). We have recently reported a few polynuclear transition metal complexes (Diao, 2007a,b). As an extension of the work on the polynuclear complexes, we report herein the crystal structure of the title complex, (I).

Compound (I) is an acetate and phenolate bridged trinuclear cobalt(II) complex. The central Co atom, lying on the inversion centre, is coordinated by four O atoms from two Schiff base ligands and two O atoms from two acetate groups, forming an octahedral geometry. Each terminal Co atom is coordinated by two O and two N atoms from one Schiff base ligand and one O atom of an acetate group, forming a square pyramidal geometry.

S2. Experimental

N,N'-1,3-Propanediamine (0.1 mmol, 7.5 mg), 2-hydroxy-1-naphthaldehyde (0.2 mmol, 34.3 mg), and cobalt acetate (0.2 mmol, 50.0 mg) were dissolved in a methanol solution (20 ml). The mixture was stirred for half an hour at room temperature, giving a red solution. After allowing the solution to stand in dark for a week, brown block-like crystals were formed.

S3. Refinement

All H atoms were placed in idealized positions and constrained to ride on their parent atoms, with C—H = 0.93–0.96 Å, and with U_iso(H) values were fixed at 0.08 Ų.

Special details

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.
