The reaction of diphenyltin (IV) or triphenyltin (IV) chloride with 3,4,5‐trimethoxybenzoyl salicylahydrazone. The crystal structure of Ph2[(MeO)3C6H2C(O)N2CHC6H4O]Sn

Abstract

AbstractThe 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 SnC 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 CSnC 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.
