Stannic chloride pentahydrate(1 mmol, 0.35 g), 8-hydroxyquinoline (1 mmol, 0.15 g) and 2-methyl-8-hydroxyquinoline (1 mmol, 0.16 g) were placed in a convection tube; the tube was filled with acetonitrile and kept at 333 K. Yellow prisms of (I) were collected after a week.
Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 to 0.96 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2 to 1.5U(C). The nitrogen- and oxygen-bound ones were located in a difference Fourier map, and were refined with distance restraints of N–H = O–H 0.86±0.01 Å; their temperature factors were refined.
Data collection: APEX2 (Bruker, 2009); cell refinement: SAINT (Bruker, 2009); data reduction: SAINT (Bruker, 2009); program(s) used to solve structure: SHELXS97 (Sheldrick, 2008); program(s) used to refine structure: SHELXL97 (Sheldrick, 2008); molecular graphics: X-SEED (Barbour, 2001); software used to prepare material for publication: publCIF (Westrip, 2010).

The 8-hydroxyquinoline anion furnishes a number of compounds with both inorganic tin(IV) and organotin(IV) systems; for example, the crystal structure of dichlorobis(quinolin-8-olato)tin has been known some time back (Archer et al., 1987). The presence of a methyl substituent in the 2-position introduces steric problems (Mohammadnezhad et al., 2010); this may affect the ability of the complexes to crystallize well so that fewer such complexes have been reported. The crystal structure of dichlorobis(2-methylquinolin-8-olato)tin has only recently been reported (Lo & Ng, 2009). On the other hand, mixed chelate complexes are difficult to synthesize as the compounds disproportionate into the symmetrical derivatives.
The reaction of tin(IV) chloride with 8-hydroxyquinoline and 2-methyl-8-hydroxyquinoline in acetonitrile yields instead the salt, 8-hydroxy-2-methylquinolinium tetrachloro(quinolin-8-olato)stannate as the acetonitrile solvate (Scheme I, Fig. 1). Owing to the steric bulk of the methyl group, the 2-methy-8-hydroxyquinoline component does not engage in binding to the tin atom but merely functions as a proton abstractor. In the salt, the tin atom is chelated by the 8-hydroxyquinolinato unit and it exists in an octahedral coordination geometry. The tin-chlorine bonds trans to the chelating atoms are significantly shorter than the other tin-chlorine bonds (Table 1). The cation is linked to the anion by an O–H···O hydrogen bond; the cation is linked to solvent molecule by an N–H···N hydrogen bond (Table 2). The stannate has been spectroscopically characterized in other salts (Cunningham et al., 1977; Douek et al., 1967; Frazer & Goffer, 1996; Frazer & Rimmer, 1968; Greenwood & Ruddick, 1967).
