- Abstract
The title complex has been synthesized by the reaction of diphenyltin(IV) or triphenyltin(IV) chloride with 3,4,5-trimethoxybenzoyl salicylahydrazone and characterized by 1H, 13C, 119Sn NMR, and IR spectral studies. An X-ray analysis shows that the ligand is tridentate and approximately planar and the central tin atom is in a distorted five-coordinate trigonal bipyramidal geometry. The complex crystallizes in the monoclinic space group C2/c with a = 29.194(4), b = 10.117(1), c = 22.524(3) Å, β = 124.44(2)°, V = 5486.5(8) Å3, Z = 8. The SnC bond lengths are 2.123(9) and 2.116(7) Å, and the bond length between the tin atom and the coordinating nitrogen atom (Sn-N bond) is 2.152(6) Å. The CSnC bond angle and the bond angle between the tin atom and the two axially positioned oxygen atoms are 129.1(1) and 156.17(9)°, respectively. The structure was refined to final R = 0.056 and Rw = 0.074 for 4145 observed reflections with I > 3σ(I). © John Wiley & Sons, Inc.
