The title compounds, (C10H11N2)2[SnCl4(CH3)2] and (C10H11N2)2[SnCl4(C6H5)2], have been prepared from the reaction of 8-methylaminoquinoline with diorganotin dichlorides. In the methyl compound, the Sn atom is coordinated to two methyl groups, which are trans with respect to each other [Sn-C 2.102 (5) and 2.103 (4) Å], and to four Cl atoms [Sn-Cl 2.442 (1), 2.461 (1), 2.894 (1) and 3.098 (1) Å]. The two long Sn-Cl bonds are trans to the short ones and their Cl atoms are hydrogen bonded to the N-H groups of the 8-methylaminoquinolinium cations. The Sn-CH3 bonds are bent away from the short Sn-Cl bonds so that the CH3-Sn-CH3 angle is 155.7 (2)°. A correlation between the C-Sn-C angle and the Sn-Cl bond lengths was observed. The anion of the phenyl compound is close to being octahedral and has exact twofold symmetry; the phenyl groups are trans with respect to each other [Sn-C 2.143 (2) Å] and Sn-Cl distances are in the range 2.497 (1)-2.672 (1) Å. Two Cl atoms are hydrogen bonded to N-H groups of the cations.
