The title compound, [Zn₃(C₂H₅)₂(C₆H₅O₃)₄]·2C₇H₈, crystallizes with one complex mol­ecule solvated by two mol­ecules of toluene in the asymmetric unit. The Zn^II ions are coordinated by two terminal ethyl (Et) groups and four maltolate ligands, which act as μ₃- and μ₂-bridges. The metal atoms are arranged in an incomplete cubane Zn₃O₄ core structure, derived from one EtZnO₃ tetra­hedron, one EtZnO₄ bipyramid and one ZnO₆ octa­hedron, sharing common corners. The structure is stabilized by weak C—H...O and C—H...π inter­actions.

S1. Comment

In recent years alkoxo zinc complexes have attracted much attention for their use as initiators for the ring-opening polymerization of cyclic esters (Chamberlain et al., 2001), metallotherapeutic drugs (Thompson et al., 2006), and precursors of electroluminescent (Kaplunov et al., 2012) and ceramic materials (Boyle et al., 2004). In this contects have also been investigated so for related zinc–maltolate complexes (Ahmed et al., 2000; Thompson et al., 2004; Petrus & Sobota, 2012a, 2012b).

We describe here the solid state structure of zinc complex [Zn₃(Et)₂(MalO)₄] (where MalOH = maltol), solvated by two molecules of toluene, (Fig. 1). The title zinc alkoxide has been previously reported in the monosolvated form [Zn₃(Et)₂(MalO)₄]^.C₇H₈, which crystallizes in the triclinic space group P1 (Petrus & Sobota, 2012a). The molecular structure comprises a trimer, containing incomplete cubane Zn₃O₄ core structure with different coordination modes around each zinc atoms (Maxim et al., 2008; Romero et al., 2010). The Zn1 ion is coordinated in a tetrahedral manner to one ethyl and two maltolate ligands in a monodentate coordination mode through atoms O11 and O17. The Zn2 atom is five-coordinated with EtZnO₄ enviroment, comprise with zinc bonded ethyl group and three alkoxy (O3, O11, O23) and one carbonyl (O12) oxygen atoms from three maltolate ligands. The geometry around the Zn2 centre can be considered as distored trigonal bipyramid, as confirmed by the metric shape parameters S(Oh) = 3.59 (Alvarez et al., 2002). The Zn3 ion is six-coordinated by three maltolate ligands in a bidentate chelating mode through the O atoms of alkoxy and carbonyl groups, forming five-membered Zn3/O3/C3/C4/O4, Zn3/O17/C17/C18/O18 and Zn3/O23/C23/C24/O24 chelate rings. The first of these metallacycles is twisted about the Zn3—O3 bond, while the rest have a conformation based on an envelope with the Zn3 atom as the envelope flap. The unsual elongated Zn2—O3 bond, i.e. by about 0.56 Å from the average Zn—O bond lengths within the Zn₂O₂ diamond cores, results in a high deformation of the central core geometry (Table 1). The title complex shows weak intermolecular C—H···O interactions between the trinuclear units and adjacent molecules to link them into extended chain (Table 2). The trinuclear cluster is also stabilized by C—H···π interactions with solvent molecules (Table 2).

S3. Refinement

Reported crystal showed weak reflections, especially at high diffraction angle, so these were omitted from the refinement for θ > 27°. All non-H atoms, were refined anisotropically. All H atoms were geometrically positioned and treated as riding on their parent atoms, with C—H = 0.95 Å for the aromatic, 0.98 Å for the methyl and 0.99 Å for the methylene with U_iso(H) = 1.5 U_eq(C) for methyl H atoms or 1.2 U_eq(C) otherwise.

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.
