Chemistry is an experimental science, and the best way to enjoy it and learn about it is performing experiments. COA of Formula: C7H5NO2S2. Introducing a new discovery about 27148-03-4, Name is Benzo[d]isothiazole-3(2H)-thione 1,1-dioxide
Synthesis and structural analysis of new palladium(II) thiosaccharinates with triphenylphosphane or diphosphanes
A series of palladium(II) thiosaccharinates with triphenylphosphane (PPh3), bis(diphenylphosphanyl)methane (dppm), and bis(diphenylphosphanyl)ethane (dppe) have been prepared and characterized. From mixtures of thiosaccharin, Htsac, and palladium(II) acetylacetonate, Pd(acac)2, the palladium(II) thiosaccharinate, Pd(tsac)2 (tsac: thiosaccharinate anion) (1) was prepared. The reaction of 1 with PPh 3, dppm, and dppe leads to the mononuclear species Pd(tsac) 2(PPh3)2MeCN (2), [Pd(tsac)2(dppm)] (3), Pd(tsac)2(dppm)2 (4), and [Pd(tsac) 2(dppe)].M.eCN (5). Compounds 2, 4, and 5 have been, prepared also by the reaction, of Pd(acac)2 with the corresponding phosphane and Htsac. All the new complexes have been characterized by chemical analysis, UV/Vis, IR, and Raman spectroscopy. Some of them, have been, also characterized by NMR spectroscopy. The crystalline structures of complexes 3, and 5 have been studied by X-ray diffraction techniques. Complex 3 crystallizes in the monoclinic space group P21/n with a = 16.3537(2), b = 13.3981(3), c = 35.2277(7) A, ss = 91.284(1), and Z = 8 molecules per unit cell, and complex 5 in Pl1/n with a = 10.6445(8), b = 26.412(3), c = 15.781(2) A, beta = 107.996(7), and Z = 4. In compounds 3 and 5, the palladium ions are in a distorted square planar environment. They are closely related, having two sulfur atoms of two thiosaccharinate anions, and two phosphorus atoms of one molecule of dppm or dppe, respectively, bonded to the PdII atom. The molecular structure of complex 3 is the first reported for a mononuclear PdII dppm-thionate system.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. COA of Formula: C7H5NO2S2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 27148-03-4, in my other articles.
