Experimental

R factor = 0.039; wR factor = 0.094; data-to-parameter ratio = 18.7. The SnIV cation in the title compound, [Sn(CH3)2-(C10H8NO)2], is N,O-chelated by two 2-methylquinolin-8-olate anions and coordinated by two methyl groups in a skew-trapezoidal bipyramidal geometry. In the molecule, the two quinoline ring systems are twisted to one another at 10.91 (18). The dimethyltin skeleton [C—Sn—C = 149.6 (2)] is bent over the longer edge of the trapezoid that is defined by the four chelating atoms. Weak intermolecular C—H O hydrogen bonding occurs in the crystal. Related literature For ethylpropylbis(2-methyl-8-quinolinato)tin(IV), see: Das et al. (1984)
