Twelve diorganotin(IV) complexes of 2-quinaldate R2Sn(2-quin) 2 and R2SnCl(2-quin) have been synthesized by dealkyltion reactions of 2-quinaldic acid (2-quinH) with (R3Sn)2O (R = PhCH2 1, 2-ClC6H4CH2 2, 2-FC 6H4CH2 3, 4-FC6H4CH 2 4, 4-CNC6H4CH2 5, Ph 6, 2,4-Cl2C6H3CH2 7) and R 3SnCl (R = 2-ClC6H4CH2 8, 4-ClC 6H4CH2 9, 2-FC6H4CH 2 10, 4-FC6H4CH2 11, PhCH 2 12), and all the complexes have been characterized by elemental analysis, IR and multinuclear NMR (1H, 13C, 119Sn) spectroscopies. The structures of (4-FC6H 4CH2)2Sn(2-quin)2 · 2CH 3CN (4) and {[(2-ClC6H4CH2) 2Sn(2-quin)Cl]2 · CH3OH}n (8) have been determined by X-ray diffraction. Studies show that complex 4 is a monomer with the central tin atom six-coordinated in a skew-trapezoidal- bipyramidal geometry and complex 8 is a one-dimensional polymer with the tin atom six-coordinated. Studies also show that the nitrogen atoms of the 2-quin ligand are coordinating to the tin atoms for all of the 12 complexes.
