Abstract
Five new oxalato, hydrogenoxalato and hydrogenocarbonato adducts (three) and complexes (two) obtained on allowing (Et3NH)HC2O4 or (Et3NH)2C2O4 to react with SnPh3Cl have been studied by infrared spectroscopy, then discrete structures suggested on the basis of spectroscopic data. The anions behave as monochelating ligands, the environments around the metallic centres being octahedral. In two of the compounds, the benzene molecules obtained in situ are lattice. In all these structures when considering the cation involved in extra hydrogen bonds, a supramolecular architecture may be obtained.
Highlights
During the past few decades, the synthesis of new molecules belonging to organo- and halotin(IV) family have been of great research interest worldwide due to their applications in medicine and industry and for structural considerations [1,2,3,4,5].In this dynamic our group has initiated here the study of the interactions between (Et3NH) HC2O4 or (Et3NH)2C2O4 and SnPh3Cl which has yielded the five studied adducts and complexes
(Et3NH) HC2O4(L1) -[%Calculated (% Found): % C = 50.25(50.19), % H = 8.96(8.67), % N = 7.32(7.42)]- and (Et3NH)2C2O4 (L2) -[ % C = 57.50(57.10), % H = 11.03(10.87), % N = 9.58(9.53)]- have been obtained as crystals on semi- or totally neutralizing H2C2O4 with Et3N in water and allowing the obtained solution to evaporate in the oven at 60°C
General considerations It seems worthy to outline the fact that the three first compounds -hydrogenoxalato- were obtained after a slow solvent evaporation while the two last ones -oxalato- were precipitates
