Synthesis and characterization of ionic organotin compounds [R2SnCl2(2-quin)]−(HNEt3)+ and crystal structures of [(2,4-Cl2-C6H3CH2)2SnCl2(2-quin)]−(HNEt3)+

Synthesis and characterization of dimeric organotin compounds {[(ArCH2)2 Sn(2-quin)]2O}2 and crystal structure of {[(2-ClC6 H4CH2)2Sn(2-quin)]2O}2

“…This finding may be consistent with previous studies, which suggest that only quinoline and pyridine type N atoms, present in the carboxylate R group, coordinate to Sn [15][16][17]. [27]; moreover, broad signals occur for ligand atoms in compounds 1-10, which further suggest the occurrence of two different types of 2-quin species.…”

Synthesis and structural characterizations of diorganotin(IV) complexes with 2-pyrazinecarboxylic acid

“…Atom O(4) does not make any significant contacts with the tin atoms. As for the second ligand, the C(6)-O(4) bond at 1.120(12) Å is shorter than the C(6)-O(3) bond at 1.265(11) Å . A weak SnÁ Á ÁN interactions exist between the Sn atom and the adjacent nitrogen atom, thereby forming a chelate with a five-membered ring.The endocyclic tin atom, Sn…”

“…Di-n-octyltin oxide and 2-pyrazinecarboxylic acid were used as received. The (ArCH 2 ) 2 SnO were prepared by the reported method [12]. The melting points were obtained with Kofler micro-melting points apparatus and were uncorrected.…”

Self-assembly of triorganotin(IV) or diorganotin(IV) moieties and 2-methylpyrazine-5-acid: Syntheses, characterizations and crystal structures of monomeric, polymeric or tetranuclear macrocyclic compounds

“…n Bu 3 SnCl, (CH 3 ) 2 SnCl 2 , n Bu 2 SnO, Ph 2 SnO, and 2-methylpyrazine-5-acid were used as received. The series of triorganotin(IV) chloride (for 1-7) were prepared by the reported method [6]. The melting points were obtained with Kofler micro-melting points apparatus and were uncorrected.…”
