Synthesis, Spectral Characterization and X-Ray Crystal Structure of Some Triphenyltin(IV) Carboxylate Compounds
The crystal and molecular structures of triphenyltin(IV) carboxylates have been determined by X-ray crystallography. The Ph3Sn(O2CC6H3-2,6-F2)c˙EtOH (1) complex is a five-coordinate monomer with an ethanol group attached to the Ph3Sn group [O(1)-Sn(1)-O(3) = 171.5(1)°; Sn(1)-O(1) = 2.151(2) Å; Sn(1)-O(3) = 2.444(2) Å]. In contrast, the Ph3Sn(O2CC6H3-5-NH2-2-Cl) (2) compound [Sn(1)-O(1) = 2.359(2) Å; Sn(1)-O(2A) = 2.224(2) Å; C(19)-O(1) = 1.250(4) Å; C(19)-O(2) = 1.269(4) Å; O(1)-Sn(1)-O(2A) = 172.2(1)°; O(1)-C(19)-O(2) = 124.5°] is polymeric because of the presence of bidentate carboxylate ligands bridging two tin atoms in trans-R3SnO2 arrangement. This results in a five-coordinate trigonal bipyramidal geometry around the Sn atom with two apical oxygen atoms and three equatorial phenyl groups. The crystal structure of Ph3Sn(O2CC6H3-2-NH2-4-Cl) (3) shows that the tin atom exists in a distorted tetrahedral geometry defined by three ipso-C atoms of the phenyl groups and the O(1) atoms of the ester group. The geometry of each complex is supported by spectroscopic (IR and NMR) data.
