Chloro­(μ-6-methyl­pyridine-2-carboxyl­ato)bis­(6-methyl­pyridine-2-carboxyl­ato)triphenyl­chromium(III)­tin(IV) chloro­triphenyl­tin(IV)

The title compound, [CrSn(C₆H₅)₃(C₇H₆NO₂)₃Cl][Sn(C₆H₅)₃Cl(CH₄O)], was obtained from the reaction of Ph₃SnCl with the complex [Cr(C₇H₆NO₂)₃] in methanol. The structure contains [Ph₃SnCl(MeOH)] (A) and [Ph₃SnClCr(C₇H₆NO₂)₃] (B) mol­ecules. In mol­ecule A, the Sn atom of Ph₃SnCl is coordinated by one methanol mol­ecule. In mol­ecule B, the Sn atom of Ph₃SnCl is coordinated by one carboxyl­ate O atom of [Cr(C₇H₆NO₂)₃]. Mol­ecules A and B are connected through an O—H...O hydrogen bond between a carboxyl­ate O atom and the methanol OH group. Weak C—H...Cl inter­actions and O—H...O hydrogen bonds extend the components of (I) into a two-dimensional network.

S1. Comment

Organotin compounds have attracted much interest, not only because of their applications as catalysts in organic reactions (Orita et al., 1998), but also for use in medicinal chemistry (Arakawa, 1998). For example, the triorganotin compounds, R₃SnX, have been known for several years as having a specific action on mitochondrial oxidative phosphorylation (Barnes & Magos, 1968). To the best of our knowledge, little attention (Döring et al., 1997; Yang et al., 2006) has been given to heterobimetallic organotin compounds. It is known that R₃Sn⁺ cations usually prefer a trigonal–bipyramidal (tbp) configuration. Thus, triorganotin compounds are good Lewis acids, despite the fact that they carry three R groups. Given the Lewis acidity of triorganotin compounds, a complex with surplus coordinating atoms can react with triphenyltin to form an adduct. We report here the crystal structure of such a compound, [Ph₃SnClCr(C₇H₆NO₂)₃][Ph₃SnClMeOH], (I).

As shown in Fig. 1, compound (I) possesses two kinds of molecules, [Ph₃SnClMeOH] (A) and [Ph₃SnClCr(C₇H₆NO₂)₃] (B). In molecule A, the Sn atom of Ph₃SnCl is coordinated by one methanol molecule, the C atom of which is disordered over two positions with unequal populations for each orientation (the ratio of the occupancies of C58–C59 is 1.27:1). Molecule B contains Ph₃SnCl which is coordinated by one carboxylate O atom of a [Cr(C₇H₆NO₂)₃] fragment. In the latter, the Cr centre is six-coordinated by N and O atoms of three 6-methylpyridine-2-carboxylate anions, displaying a distorted octahedral configuration. The three N atoms are meridional, as are the three O atoms.

Each Sn atom of (I) shows a trans-ClSn(R₃)O trigonal–bipyramidal coordination environment, with three phenyl groups in equatorial positions (C19, C25 and C31 for Sn1, and C1, C7 and C13 for Sn2) and Cl and O atoms in axial positions (Cl1 and O4 for Sn1, and Cl2 and O7 for Sn2). The axial-O—Sn—axial-Cl angles are 179.14 (7) (O4—Sn1—Cl1) and 175.21 (7)° (O7—Sn2—Cl2), so the structures can be described as slightly distorted trigonal bipyramids. Molecules A and B are connected through an O—H···O hydrogen bond between the carboxylate O atom and the hydroxyl H atom of methanol.

In the complex [Cr(C₇H₆NO₂)₃], the Cr—O distances of 1.944 (2), 1.957 (2) and 1.931 (2) Å are near the values found in other chromium complexes with pyridine-2-carboxylate (Steams & Armsbong, 1992). However, the Cr—N distances of 2.115 (3), 2.090 (3) and 2.088 (3) Å are somewhat longer. The Sn—O bond distances of (I) are longer than the value found in (Ph₃Sn)₂O (1.955 Å; Glidewell & Liles, 1978), but shorter than the value in [Sn₂(C₆H₅)₆(C₈H₄O₄)] (2.724 Å; Zhang et al., 2006). The Sn—Cl bond distances are significantly longer than those found for Ph₃SnCl (2.321 and 2.315 Å; Bokii et al., 1970).

As shown in Fig. 2 and Table 2, molecules B form a one-dimensional zigzag chain via weak C—H···Cl interactions between the C atoms of the pyridine rings and Cl anions bound to Sn atoms. Adjacent one-dimensional chains are parallel to each other. The zigzag chains are connected together through O—H···O hydrogen bonds and weak C—H···Cl interactions between molecules A and B to form a two-dimensional network. There are no π–π interactions between the aromatic rings in the structure of (I).

The molecular structure of (I) can be viewed as a donor–acceptor adduct, in which the electron-rich Cr complex interacts with the electrophilic Sn centre, without causing the loss of Cl⁻ anions. It can be predicted that the Lewis acidity of organotin can facilitate the formation of adducts. Thus, it is conceivable that compounds with new properties can be prepared by introducing a second metal into organotin compounds.

S2. Experimental

A mixture of NaOH (0.012 g, 0.3 mmol) and 6-methylpyridine-2-carboxylic acid (0.041 g, 0.3 mmol) in water (10 ml) was stirred for 10 min, and then CrCl₃·6H₂O (0.027 g, 0.1 mmol) was added. A purple solid was collected by filtration after stirring for 30 min. The solid was redissolved in methanol (15 ml), and Ph₃SnCl (0.039 g, 0.1 mmol) was added to the purple solution. After refluxing for 2 h, the mixture was filtered. Purple block crystals of (I) were obtained by evaporating the filtrate at room temperature for several days.

S3. Refinement

The H atoms on the disordered methyl group of methanol were not located. Other H atoms bound to carbon were refined using a riding model, with C—H = 0.93 Å and U_iso(H) = 1.2U_eq(C) for aromatic H, and C—H = 0.96 Å and U_iso(H) = 1.5U_eq(C) for methyl H. The hydroxy H atom was located in a difference Fourier map. Its coordinates were refined and its U_iso(H) was set to 1.5 U_eq(O).

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.
