In the title compound, [Hg3(C6F4)3(C3H8O2)2], two O atoms from one 2-meth­oxy­ethanol ligand and one O atom from the second 2-meth­oxy­ethanol ligand coordinate three HgII atoms [Hg—O = 2.765 (7)–2.890 (8) Å] in the trimeric organomercurial Lewis acid (o-C6F4Hg)3. The hy­droxy groups are involved in formation of intra- and inter­molecular O—H⋯O hydrogen bonds; the latter link two mol­ecules into centrosymmetric dimers. An extensive net of weak inter­molecular C—H⋯F inter­actions further consolidates the crystal packing.

As an organomercurial compound trimeric perfluoro-o-phenyl­ene mercury (I) has numerous adducts with aldehydes, ketones, amides, nitriles, phospho­ramides, and sulfoxides (Taylor et al., 2007). Formation of complexes involving I with oxygenated Lewis bases similar to 2-meth­oxy­ethanol (II) had been observed before (Tikhonova et al., 2002). The studies of this type of coordination are important due the effect of I on the keto-enol tautomerism (Tikhonova et al., 2013) as well on the activation of carbonyl compounds (Tikhonova et al., 2002). Acting as Lewis acid I had proven catalyze the Diels-Alder reaction between thio­noester and cyclo­penta­diene (Lee et al., 1999). Besides II is not a strong Lewis base it exhibits shorter Hg···O contacts than the sum of the van der Walls radii (Hg = 1.7-2 Å, O = 1.52 Å).

In the title compound (Fig. 1), the coordinating Hg···O contacts range from 2.765 (7) to 2.890 (8) Å. These short contacts are in the same range as those described for carbonyl compounds (Tikhonova et al., 2002). The present complex [I·(II)2] has two II molecules per one I molecule. The hy­droxy groups are involved in formation of intra- and inter­molecular O—H···O hydrogen bonds (Table 1), and the latter ones link two complex molecules into centrosymmetric dimers. An extensive net of weak inter­molecular C—H···F inter­actions (Table 1) consolidate further the crystal packing. To the best of our knowledge this complex is the first coordination example of a non-cyclic ether with macrocycle I. That indicates a possibility of I to form complexes with non-cyclic ethers, like polyethyl­ene glycol derivatives.

Synthesis and crystallization top

Trimeric perfluoro-o-phenyl­ene mercury (I) was synthesized according to the known procedure (Sartori & Golloch, 1968). The title compound [I·(II)2] was obtained by dissolving pure I in II, followed by slow evaporation of the solvent until single crystals were obtained.

Refinement top

All hydrogen atoms were placed in the calculated positions with O—H = 0.84 Å, C—H = 0.98–0.99 Å and refined as riding, with Uiso(H) = 1.2–1.5 Ueq of the parent atom.

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.
