THE REACTION OF DIPHENYLTIN(IV) OR TRIPHENYLTIN(IV) CHLORIDE WITH 3,4,5-TRIMETHOXYBENZOYL SALICYLAHYDRAZONE - THE CRYSTAL-STRUCTURE OF PH(2)[(MEO)(3)C6H2C(O)N2CHC6H4O]SN

The title complex has been synthesized by the reaction of diphenyltin( IV) or triphenyltin(IV) chloride with 3,4,5-trimethoxybenzoyl salicyla hydrazone and characterized by H-1, C-13, Sn-119 NMR, and IR spectral studies. An X-ray analysis shows that the ligand is tridentate and app roximately planar and the central tin atom is in a distorted five-coor dinate trigonal bipyramidal geometry The complex crystallizes in the m onoclinic space group C2/c with a = 29.194(4), b = 10.117(1), c = 22.5 24(3) Angstrom beta = 124.44(2)degrees V = 5486.5(8) Angstrom(3), Z = 8. The Sn-C bond lengths are 2.123(9) and 2.116(7) Angstrom, and the b ond length between the tin atom and the coordinating nitrogen atom (Sn -N bond) is 2.152(6) Angstrom. The C-Sn-C bond angle and the bond angl e between the tin atom and the two axially positioned oxygen atoms are 129.1(1) and 156.17(9)degrees, respectively. The structure was refine d to final R = 0.056 and R(w) = 0.074 for 4145 observed reflections wi th I > 3 sigma(I). (C) 1996 John Wiley & Sons, Inc.
