Syntheses, Characterization and Crystal Structures of 1D and 2D Organotin Polymers Containing 3-Methyladipic Acid Ligand

“…2.282 Å ) and 2.101-2.131 Å (av. 2.113 Å ), which is consistent with those reported for other triorganotin carboxylates[39].…”

Synthesis, Characterization and Antimicrobial Activity of Some Organotin (IV) Complexes with a Potassium Hydrogen Ethanedioate Ligand

“…The band at 3486 cm -1 which appeared in the free ligand as the υ(O-H) stretching vibrations but absent in compounds 1-4, indicated metalligand bond formation through these sites [25]. The red shifts of the bands with respect to the free acid also served to confirm the formation of organotin carboxylates [10]. The binding mode of ligand to tin atom was determined by the difference between the asymmetric and symmetric carboxylate stretching vibrations, Δυ = υ asym (COO) and υ sym (COO) [26].…”

“…The high coordination ability of tin, especially its ability to participate either in weak or strong intra or intermolecular coordination [6], has given organotin (IV) chemistry wide recognition. Tin compounds have a fascinating solution and solid phase chemistry [7]. The coordination characteristics of tin and the structures differ dramatically in solution and in solid state when a nucleophilic group is present in the tin moiety or when an organic group is linked by a Sn─C bond [8] and bears additional functionality with donor properties due to the presence of O, N and S as donor atoms [2]- [6].…”

“…Organotin (IV) carboxylates are widely studied compounds with structural diversity and finds pharmaceutical applications [2] especially with reference to their antitumour [8] and anti-tuberculosis [9] activities. In the presence of additional coordinating atoms, some organotin carboxylates have fascinating structures, such as hexameric cyclic forms with a wide variety of coordination geometries [4], [10]. The combination of steric and electronic factors determine the specific structure adapted by a particular carboxylate [4], which could be monomeric, dimeric, tetrameric, oligomeric, cyclic and hexameric drum.…”

“…The combination of steric and electronic factors determine the specific structure adapted by a particular carboxylate [4], which could be monomeric, dimeric, tetrameric, oligomeric, cyclic and hexameric drum. It has been reported that the different structural types are formed due to the presence of additional coordinating sites (S, N or O) along with a carboxylic moiety [7]. In recent years, organotin (IV) carboxylates have been a subject of interest for some time because of their biochemical and commercial applications.…”
