S1. Chemical context

\ Only a few polynuclear heterometallic compounds containing barium and zinc connected by carboxyl­ate bridges are known (Akine et al., 2006, 2009, 2010; Zhang et al., 2012; Bo et al., 2013). We have been studying the reactions of the tri­phenyl­acetate anion with metal salts and we have obtained several anhydrous polynuclear Mn^II tri­phenyl­acetate-containing clusters (Utko et al., 2014). The complexes with some metals (for example: Fe, Ni, Cu, Ru, Rh, Ag) are reported in the literature (Yamanaka et al., 1993; Cotton et al., 1994; Akhbari & Morsali, 2010; Barberis et al., 2001; Cadiou et al., 2002; Do & Lippard, 2011). However, among polynuclear complexes with tri­phenyl­acetate ligands, Ba–Zn clusters have not previously been reported. In the present work, we aimed to create a mixed-ligand compound containing zinc and barium metals, using barium tri­phenyl­acetate as a means of displacing chlorine atoms from zinc chloride. This procedure for removal of chlorine using tri­phenyl­acetate was successfully carried out in a reaction leading to the formation of a mixed-metal complex with a [Ba₄Ti₂] core (Kosińska-Klähn et al., 2014). In the present paper we report the synthesis and structural characterization of a dinuclear Ba–Zn complex, namely µ-chlorido-1:2κ²Cl:Cl-chlorido-2κCl-bis­(2-\ meth­oxy­ethanol-1κO)bis­(2-meth­oxy­ethanol-1κ²O,O')\ bis­(µ-tri­phenyl­acetato-1:2κ²O:O')bariumzinc, (I), and the structure is discussed herein.

S2. Structural commentary

In the structure of (I), the asymmetric unit contains one dinuclear complex of [BaZn(Ph₃CCOO)₂(CH₃OCH₂CH₂OH)₄Cl₂] (Fig. 1), in which the dinuclear [BaZn]⁴⁺ cationic core is bridged by two carboxyl­ate arms of the tri­phenyl­acetate ligands in a η¹:η¹:µ² coordination mode and by one bridging chlorine atom (µ₂-Cl). To the best of our knowledge, the (µ₂-Cl) bridge between zinc and barium has been found for the first time in the structure of the title compound. The Ba···Zn distance in this dimer is 3.9335 (11) Å. Oxygen atoms have the largest contribution to the filling of the coordination sphere of barium [Ba—O bond-length range, 2.6925 (19)– 2.985 (2) Å; Table 1]. Barium is bonded to one bridging chloride atom (µ₂-Cl), two O-atoms of two carboxyl­ate groups and also to six O atoms from the 2-meth­oxy­ethanol ligands (four from two bidentate O,O¹ chelate inter­actions and two from monodentate inter­actions). 2-Meth­oxy­ethanol is coordinated only to the Ba atom. The coordination mode is achieved in two different ways. Two terminal molecules representing an η¹:η¹ mode form two five-membered rings completed by the barium atom. Two other molecules of 2-meth­oxy­ethanol coordinate to Ba only through the hydroxyl O atoms.

Zinc is four-coordinated with a distorted tetra­hedral ZnO₂Cl₂ stereochemistry (Table 1), with Zn—Cl1 (bridging) = 2.2595 (10) Å and Zn—Cl2 (monodentate) = 2.2653 (9) Å and Zn—O (both from the bridging tri­phenyl­acetate groups = 1.96817 (2) and 1.9683 (18) Å). A comparison with other structurally characterized mixed-metallic zinc–barium complexes reveals that the Zn–Cl–Ba linkage has been observed for the first time in the present compound. There are only a few compounds containing both of these metals and only one is a dinuclear structure, with a distance between the atoms of 3.629 (2) Å, significantly shorter than in the title complex [3.9335 (11) Å], but zinc and barium are connected only via bridging oxygen atoms (µ₂-O) from organic ligands (Van Veggel et al., 1989). Also, in other structures without carboxyl­ate bridges, the Zn···Ba distances are often much shorter than in the title complex with values in the range 3.4325 (5) to 4.850 (3) Å (Westerhausen et al., 2001, 2006; Baggio et al., 2004; Łukasz et al., 2008). In those cases where the oxygen atom (µ₂-O) and also carboxyl­ates connect zinc and barium, the Zn···Ba distance is not longer than 3.638 (1) Å (Akine et al., 2006, 2009, 2010). In a polymeric structure where zinc and barium atoms are bridged via two carboxyl­ate arms and also via one molecule of water, the distance between them is 4.0208 (5) Å (Zhang et al., 2012).

S3. Supra­molecular features

In the crystal, there are intra­molecular O—H···O hydrogen bonds (Table 2). One is formed between a hydroxyl group O1I and an O-atom acceptor from the ether group (O2H) of a 2-meth­oxy­ethanol ligand, the second is formed between a hydroxyl group O1H and an O-atom acceptor from a carboxyl group (O3) of a Ph₃CCOO^- ligand (Fig. 2). The presence of electronegative atoms (oxygen and chlorine) also leads to the occurrence of inter­molecular hydrogen bonds in the crystal structure. The neighbouring dinuclear molecules inter­act through O—H···O, O—H···Cl and C—H···Cl hydrogen bonds. The first one occurs between the hydroxyl group O1G and an ether O-atom acceptor O2Iⁱ, the second occurs between the hydroxyl group O1J and the terminal chlorine atom Cl2ⁱⁱⁱ. In the third inter­action, the H-donor atom is from a 2-meth­oxy­ethanol carbon (C2I), with the bridging chlorine atom (Cl1I)ⁱⁱ acting as the H-atom acceptor (for symmetry codes, see Table 2). A two-dimensional network structure is generated (Fig. 3), lying parallel to (001).

S4. Synthesis and crystallization

For the preparation of Ba(Ph₃CCOO)₂, a mixture of metallic barium (0.521 g, 3.8 mmol), tri­phenyl­acetic acid (2.209 g, 7.66 mmol), C₆H₅CH₃ (50 ml) and THF (10 ml) was stirred at 363– 373 K for 24 hours until all the metal had reacted. The solution, which included a white precipitate, was concentrated to about 20 ml and then hexane (50 ml) was added while stirring, which led to further precipitation. The product was filtered on a Schlenk flask (yield: 2.520 g, 93.26%). Elemental analysis (%) calculated for Ba(Ph₃CCOO)₂: C 67.48, H 5.38, Ba 19.29; found: C 67.56, H 5.51, Ba 19.44. Solid ZnCl₂ (0.273 g, 2.0 mmol) and Ba(Ph₃CCOO)₂ (1.426 g, 2.0 mmol) were then added to a solution of CH₃OCH₂CH₂OH (30 ml) and C₆H₅CH₃ (15 ml) and the resulting mixture was stirred under a nitro­gen atmosphere for 24 hours. The solution was filtered and then concentrated to about 20 ml. Afterwards 20 ml of hexane was funneled into the reaction solution, leading to the creation of two layers and the mixture was left to crystallize at room temperature. After one week, colorless crystals suitable for the X-ray experiment were obtained (1.289 g, yield: 55.83%). Knowledge of the molecular structure of the final product enables representation of the chemical equation for the reaction as: ZnCl₂ + Ba((C₆H₅)₃CCOO)₂ + 4 (CH₃OCH₂CH₂OH) → [BaZnCl₂((C₆H₅)₃CCOO)₂(CH₃OCH₂CH₂OH)₄]. Elemental analysis: (%) calculated for the complex: C 54.14, H 5.38, Cl 6.3, Zn 5.67, Ba 11.91; found: C 52.94, H 5.67, Zn 5.48, Ba 11.24.

S5. Refinement details

Crystal data, data collection and structure refinement details are summarized in Table 3. All C-bonded H atoms were positioned geometrically and treated as riding atoms: methyl H atoms were constrained to an ideal geometry, with C—H = 0.98 Å and U_iso(H) = 1.5U_eq(C); the remaining H atoms were afixed to C atoms, with Csp²—H = 0.95 Å and Csp³—H = 0.99 Å, and with U_iso(H) = 1.2U_eq(C). The locations of H atoms of the hydroxyl groups were determined from a difference-Fourier map and finally constrained to ride on their parent atoms, with U_iso(H) = 1.5U_eq(O).

Special details

Experimental. The O-bonded H atoms were found from a difference-Fourier map. These H atoms were included in the refinement with constraint:;finally with instruction Afix 3.

Absorption correction: CrysAlis RED (Oxford Diffraction, 2010), employing an analytical numeric absorption correction using a multifaceted crystal model based on expressions derived by R.C. Clark & J.S. Reid (Clark & Reid, 1995).

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.
