cis-Di­chloro­tetrakis(2-mercapto-1-tert-butyl­imidazole)­lead(II)

The crystal and molecular structure of the title compound, [PbCl₂(C₇H₁₂N₂S)₄], the first mononuclear lead complex containing a 2-mercapto-1-alkyl­imidazole ligand to be structurally characterized, has been determined by single-crystal X-ray diffraction. The six-coordinate Pb atom displays a distorted octahedral geometry and is surrounded by four thione groups and two cis chloro ligands, with average Pb-S and Pb-Cl bond distances of 2.946 (3) and 3.058 (2) Å, respectively.

S1. Comment

The coordination chemistry of lead with sulfur-donor ligands is surprisingly underdeveloped despite the purported thiophilicity of this metal. According to a recent survey, only about 16% of all Pb^II compounds in the Cambridge Structural Database (CSD; Version 5.24, November 2002; Allen, 2002) contain one or more sulfur-donor groups (Claudio et al., 2003). Heterocyclic thione and thionate ligands are no exception, and very few derivatives of lead have been isolated with such donors despite the large number of complexes obtained with them for both transition and main group metals (Raper, 1985; Akrivos, 2001). In view of this imbalance and because of our interest in the coordination chemistry of lead with simple thione-type donor ligands, we set out to prepare new complexes with N-substituted mercaptoimidazoles. We report here the synthesis, characterization and structure of cis-dichlorotetrakis(2-mercapto-1-tert-butylimidazole)lead(II), (I), the first mononuclear lead complex containing a 2-mercapto-1-alkylimidazole ligand.

The crystal and molecular structure of (I) was determined by single-crystal X-ray diffraction (Fig. 1). The Pb atom in cis-Pb(Hmim^tBu)₄Cl₂ is coordinated to the thione moieties of four mercaptoimidazole groups and to two adjacent chloro ligands in a distorted octahedral environment, with the trans and cis angles in the approximate ranges 154–170 and 82–112°, respectively. The two Pb—S distances to the thione ligands trans to the chlorides (ca 2.89 Å) are slightly shorter than those for the mutually trans thiones (ca 3.00 Å). While these values are only moderately longer than the corresponding bond lengths to the terminal methimazole groups in the dinuclear derivative Pb₂(Hmim^Me)₆(NO₃)₄ (ca 2.84 Å; Bristow et al., 1987), they are comparable to those found in other Pb^II complexes with thioureas or heterocyclic thiones (Goldberg & Herbstein, 1972; Herbstein & Kaftory, 1972; Williams et al., 1992). It is also interesting to note that the average C—S bond length in cis-Pb(Hmim^tBu)₄Cl₂ (ca 1.71 Å) is very similar to the corresponding averages found for the group 12 metal derivatives (Hmim^tBu)₄MBr₂ (M = Zn, Cd, Hg) (ca 1.72 Å) or even in free Hmim^tBu (1.70 Å; White et al., 2003). The Pb—Cl bond lengths, 3.037 (2) and 3.079 (2) Å, while longer than the mean value found in the CSD for such terminal interactions in six-coordinate Pb^II (2.87 Å), are still within the range of observed distances for such bonds (2.617–3.348 Å; Allen & Kennard, 1993).

S2. Experimental

A solution of 2-mercapto-1-tert-butylimidazole (0.150 g, 0.960 mmol) in methanol (1 ml) was added to a stirred solution of PbCl₂ (0.067 g, 0.240 mmol) in water (5 ml), resulting in the immediate formation of an off-white precipitate and a pale yellow solution. After stirring the suspension for 30 min, the product was isolated by filtration and dried in vacuo for 14 h (0.126 g, 58%). NMR data (in CD₂Cl₂): ¹H δ 1.74 [s, 36H, C(CH₃)₃], 6.72 (d, ³J_H–H = 2.3 Hz, 4H, imidazole H), 6.84 (d, ³J_H–H = 2.3 Hz, 4H, imidazole H), 11.91 (br s, 4H, NH); ¹³C d 28.5 [q, ¹J_C–H = 128 Hz, 12 C, C(CH₃)₃], 59.1 [s, 4 C, C(CH₃)₃], 114.2 (d, ¹J_C—H = 176 Hz, 4 C, imidazole C), 116.3 (d, ¹J_C–H = 167 Hz, 4 C, imidazole C), 156.8 (s, 4 C, C═S).

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.
