In the title benzene-solvated heteroleptic lithium complex, [Li(C25H21P2S2)(C10H8N2)]·C6H6, the LiI ion is four-coordinated in a distorted tetra­hedral geometry by two S atoms and two N atoms of the two chelating ligands, viz. bis­(diphenyl­thio­phosphino­yl)methyl and 2,2′-bipyridine. The 2,2′-bipyridine mol­ecule is slightly twisted with a dihedral angle between the pyridine rings of 7.35 (12)°. Intra­molecular C—H⋯S hydrogen bonds are present. In the crystal, mol­ecules are stacked along the c axis by ππ inter­actions, with centroid–centroid distances of 3.6021 (15) and 3.6401 (16) Å. The crystal structure also features weak C—H⋯π inter­actions.

Comment top

Metal chelators containing sulfur are important compounds with many applications such as for metal extraction and development of antioxidant capacity (Amir et al., 2013). Thiophosphinyl ligands and their complexes, including their reactivity and applications, have been extensively studied (Amir et al., 2013; Leung, Wan & Mak, 2010; Leung, Wan, Kan & Mak, 2010; Ren et al., 2011). Our ongoing research on carbene complexes is to synthesize the dilithium salts with the pincer carbene ligand. However the title complex (I) was isolated as a monolithium salt. Herein, the synthesis and crystal strcuture of (I) was reported.

Complex (I) is a heteroleptic lithium(I) complex (Fig. 1) in which the environment around the LiI ion is distorted tetrahedral and the LiI ion is four-coordinated by the two S atoms of bis(diphenylthiophosphinoyl)methyl and two N atoms of 2,2'-bipyridine chelating ligands. The bond angles around the central metal LiI show large deviations from ideal tetrahedral geometry [N1-Li1-S1 = 101.41 (18)°, N1-Li1-S2 = 121.2 (2)°, N2-Li1-S1 = 114.67 (19)°, N2-Li1-S2 = 119.1 (2)°; and the bite angles N1–Li1-N2 = 81.54 (17)° and S1-Li1-S2 = 114.03 (17)°]. The Li-S bond lengths [2.420 (4) and 2.441 (4) Å] and Li-N bond lengths [2.030 (5) and 2.035 (5) Å] are similar to those of the previously reported heteroleptic analogue (Thirumoorthi & Chivers, 2012). Similarly, the P-S [1.9939 (9) and 2.0155 (8) Å] and P-Cmethy [1.712 (2) and 1.716 (2) Å] bond lengths are comparable to those of another similar Li(I) complex (Thirumoorthi & Chivers, 2012). The six-membered ring Li1–S1–P1–C23–P2–S2 adopts a twisted boat conformation. The 2,2'-bipyridine ring system (C1–C10/N1–N2) is slightly twisted with the dihedral angle between the two pyridine rings being 7.35 (12)°. The dihedral angle between the two C11–C16 and C17–C22 benzene rings is 86.24 (2)° whereas that between the C24–C29 and C30–C35 benzene rings is 85.99 (12)°. The bond lengths of ligand are within normal ranges (Allen et al., 1987). Intramolecular C—H···S hydrogen bonds are observed (Table 1).

The arrangement of molecules in crystal structure of (I) is illustrated in Fig. 2. Fig. 3 shows the stacking of molecules along the c axis. The molecules are stacked by π···π interactions with the centroid···centroid distances: Cg1···Cg2iv = 3.6012 (15) Å and Cg2···Cg3v = 3.6401 (16) Å; Cg1, Cg2 and Cg3 are the centroids of C1–C5/N1, C6–C10/N2 and C11–C16 rings, respectively. C—H···π weak interactions are also present (Table 1).

Experimental top

An n-hexane (2 mL) solution of n-C4H9Li (0.5 M; 1 mmol) was slowly added into a benzene (10 mL) solution of bis(diphenylthiophosphinoyl)methane (448 mg, 1 mmol) and 2,2'-bipyridine (156 mg, 1 mmol) at 195 K with stirring. After this solution was warmed up to room temperature and stirred for one hour, the solution was filtered. The filtrate was concentrated to about 2 mL under vacuum. Yellow block-shaped single crystals of the title compound suitable for x-ray structure determination were obtained when this solution was kept at room temperature for two days. Yield: 585 mg (85%).

Refinement top

Al H atoms were placed in calculated positions with d(C—H) = 0.95 Å and Uiso(H) = 1.2Ueq(C).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
