Chlorodiphenyltin(IV) and triphenyltin(IV) complexes of N-alkylated 2-amino-1-cyclopentene-1-carbodithioic acids: synthesis, spectroscopic characterization and X-ray studies

Abstract

Four new complexes, [Ph 3

Synthesis, spectroscopic characterization and crystal structures of diorganotin (IV) complexes of 2-N-propyl and 2-N-benzyl-amino-1-cyclopentene-1-carbodithioates

“…IR bands were assigned by comparison with the spectra of Bz-HACDA and Pr-HACDA and with previously reported data (Tarassoli et al, 2006;Hanif et al, 2008). A band in the 3340-3350 cm -1 region is assigned to the ν(NH) stretching mode (Chauhan et al, 1984), which shows no significant shift from that of the free ligand, indicating that this functional group is not involved in the coordination to tin.…”

“…In the last decade, various investigations have been reported on the synthesis of complexes of diorganotin(IV) (Tarassoli et al, 2006;Hanif et al, 2008) with ACDA type ligands.…”

Interplay of thermochemistry and Structural Chemistry, the journal (volume 19, 2008) and the discipline

“…In the following paper, Hanif et al [262] reported the synthesis and characterization of two triphenyltin(IV) and two chlorodiphenyltin(IV) complexes of N-substituted, N-alkylated 2-amino-1-cyclopentene-1-carbodithoic acid (ACDA) complexes: [Ph 3 Sn(isopropylACDA)], [Ph 2 SnCl (isopropylACDA)], [Ph 3 Sn(secbutylACDA)] and [Ph 2 SnCl (secbutylACDA)]. The authors used FTIR, multinuclear NMR and mass spectrometry to characterize all four complexes.…”

New tetrahedral, square-pyramidal, trigonal-bipyramidal and octahedral organotin(IV) 4-ethoxycarbonylpiperazine-1-carbodithioates: Synthesis, structural properties and biological applications

“…In methyl derivatives (1), (4) and (7) small satellites are clearly visible along with the chemical shift value of the methyl moiety, providing 2 J[ 119 Sn, 1 H] coupling values of 57, 75 and 79 Hz, respectively. These values correspond to C-Sn-C bond angle of 110°, 125°and 130°thus suggested four (1) and penta-coordinated (4 and 7) Sn [4,[18][19][20]. Chemical shifts of n-butyl and aromatic protons are difficult to assign because of their peaks multiplicity and consequently overlapping of signals.…”
