“…For example, in 4, the distances of C(9)-O(1) and C(9)-O(2) bonds are 1.307 14and 1.205(13) Å, respectivly, showing the single and double bond characteristics of C-O bonds. These features are also observed in other analogues, such as n-Bu 2 Sn (2-OC 6 H 4 C(H)=NCH(CH(CH 3 ) 2 )C(O)O) (Yin et al, 2004), n-Bu 2 Sn(3,5-Br 2 -2-OC 6 H 2 C(H)=NCH(CH(CH 3 ) 2 )C(O)O) (Tian et al, 2007), and Me 2 Sn(5-Cl-2-OC 6 H 3 C(H)=NCH(CH(CH 3 ) 2 ) C(O)O) (Tian et al, 2018).…”

“…Organotin complexes with carboxylate ligands have attracted a lot of attention because they display higher catalytic and cytotoxic activity and the diversified structures (Arjmand et al, 2014;Bantia et al 2019;Davies et al, 2008;Eng, 2017;Tian et al, 2019). Some organotin complexes of N-salicylidene-Lvaline have been synthesized, and displayed good optical and biological properties (Beltran et al, 2003;Rivera et al, 2006;Tian et al, 2005Tian et al, , 2016Tian et al, , 2018Yao et al 2017). They are synthesized by treating the corresponding oxide or hydroxide with N-salicylidene-L-valine or from the reaction of the corresponding chloride with a sodium (or potassium) N-salicylidene-L-valinate.…”

The synthesis and characterization of five new chiral dialkyltin complexes of N-salicylidene-L-valine, [2-O-3-R-5-R'C6H2C(H)=NCH(CH(CH3)2)C(O)O]SnR''2 (R, R', R'' = H, H, Me (1); H, Br, Me (2); OMe, H, Et (3); Br, Br, n-Bu (4); CH(OMe)2, Me, n-Bu (5)), have been reported. Compounds 1-5 are all (S)-enantiomers, and their crystal structures have been studied. Compound 1 displays a trimeric macrocyclic structure in which the coordination environment of each tin atom is a distorted [SnC2NO3] octahedron. In complexes 2-5, the tin atom has an intermediate geometry between trigonal bipyramidal and square pyramidal, and 3 is closer to a square pyramid. In crystals, a zigzag supramolecular chain is formed by the intermolecular C-H…O, O-H…O or Sn…O interactions.

“…However, when the coordination is broken by an external ligand (bpy and phen), the shielding of -CHOC=O is recovered again. In complex 2, the chemical environment of two pyridine rings from the ligand bpy is different due to the rigid chelate ring formed by bpy coordination to the tin atom, so that the pyridine ring displays two sets of 1 H and 13 C NMR signals (Tian et al, 2018;Van Koten and Noltes, 1976;Wang et al, 1999). The same behavior is also found in phen complex 3.…”

The complexes of 2-(menthoxycarbonyl)ethyltin chloride, MenOCOCH2CH2SnCl3⋅L (Men = Menthyl, L = benzyl phenyl sulfoxide (bpSO), 1; 2,2’-bipyridine (bpy), 2; 1,10-phenanthroline (phen), 3) and [MenOCOCH2CH2SnCl2(OCH3)]2 (4), have been synthesized and characterized by means of elemental analysis, FT-IR, NMR (1H, 13C and 119Sn) spectra. The crystal structures of 1, 3 and 4 have been determined by single crystal X-ray diffraction. The tin atoms in 1-4 are all hexa-coordinated. The tin atom in 1 adopts a distorted [CSnCl3O2] octahedral geometry with an oxygen atom of the ligand and an intramolecular coordination of the oxygen atom from the carbonyl group to the tin atom. Complex 3 possesses a distorted [CSnCl3N2] octahedral geometry with two nitrogen atoms of a chelating phen ligand. The carbonyl oxygen atom of the ester moiety is not coordinating. Compound 4 is a centrosymmetric dimer with a four-membered Sn2O2 ring, and the tin atom has a distorted [CSnCl2O3] octahedral geometry with an intramolecular C=O→Sn coordination and intermolecular methoxy bridging.
