The SnIV atom in the centrosymmetric dinculear title compound, [Sn2(CH3)2(C6H5)2(C9H6NO)2Cl2], shows a trans-C2SnNO2Cl distorted octahedral coordination [C–Sn–C = 157.83 (8)°]. The quinolin-8-olate anion chelates to the Sn atom; its O atom also binds to the inversion-related Sn atom, forming the dinuclear compound. In the weak intermolecular C—H⋯Cl hydrogen bonding links the molecules, forming supramolecular chains running along [100].

Methylphenyltin dichloride (0.35 g, 1 mmol) and 8-hydroxyquinoline (0.15 g, 1 mmol) were dissolved in methanol (10 ml) to give a faint yellow solution. The solution was set aside for the growth of crystals over a few days. Slow evaporation of methanol furnished crystals.
Hydrogen atoms were placed in calculated positions (C–H 0.95–0.98 Å) and were included in the
in the riding model approximation, with U(H) set to 1.2–1.5Ueq(C).The final difference Fourier map had a peak in the vicinity of Sn1.
The anion of 8-hydroxyquinoline is known to chelate to tin in organotin(IV) quinolinolates; however, for the chloroorganotin quinolinates, the chlorine atom sometimes participates in weak intermolecular bridging. In chloridoodiethyl(quinolin-8-olato)tin, the carbon–tin–carbon angle is opened to 140.9 (3) ° owing to a tin···chlorine contact of 3.690 (2) Å (Shi & Hu, 1987). With the bis(2-carbomethoxyethyl) analog, the tin atom is six-coordinate owing to an intramolecular bond with the oxygen atom of the organo radical (Ng et al., 1989). The chloridomethylphenyltin analog exists as a centrosymmetric dimer in which the quinolin-8-olate anion N,O-chelates to the tin atom (Fig. 1). However, its oxygen atom also binds to the inversion-related tin atom so that bridging by the chlorine atom is precluded for the trans-C2SnNO2Cl octahedral dinuclear molecule. Intermolecular weak C—H···Cl hydrogen bonding links the molecules to form the one dimensional supra-molecular chain in the
(Table 1).For related structures, see: Ng et al. (1989); Shi & Hu (1987).

The anion of 8-hydroxyquinoline is known to chelate to tin in organotin(IV) quinolinolates; however, for the chloroorganotin quinolinates, the chlorine atom sometimes participates in weak intermolecular bridging. In chloridoodiethyl(quinolin-8-olato)tin, the carbon–tin–carbon angle is opened to 140.9 (3) ° owing to a tin···chlorine contact of 3.690 (2) Å (Shi & Hu, 1987). With the bis(2-carbomethoxyethyl) analog, the tin atom is six-coordinate owing to an intramolecular bond with the oxygen atom of the organo radical (Ng et al., 1989). The chloridomethylphenyltin analog exists as a centrosymmetric dimer in which the quinolin-8-olate anion N,O-chelates to the tin atom (Fig. 1). However, its oxygen atom also binds to the inversion-related tin atom so that bridging by the chlorine atom is precluded for the trans-C2SnNO2Cl octahedral dinuclear molecule. Intermolecular weak C—H···Cl hydrogen bonding links the molecules to form the one dimensional supra-molecular chain in the crystal structure (Table 1).
