Abstract: Centrosymmeric bis[3-(4-methylcoumarinyl-7-oxy)--methoxy-1,1,3,3-tetramethyldistannoxane], [-OCH3-(CH3)2(C10H7O3)Sn-O-Sn(CH3)2]2, possesses a central rhombic Sn'2O'2 core, which is flanked on opposite sides by the Sn'O'Sn''O'' unit (where O' is the distannoxanyl O atom and O'' is the methoxyl O atom). The two Sn atoms are both five-coordinate, in a cis-C2SnO3 trigonal bipyramidal geometry [C-Sn-C 130.6 (4) and 133.3 (4)°].
