Synthesis and crystal structure of some phosphite, thiophosphite, and amidophosphite copper(I) halide complexes

Abstract

Some Cu(I) halides complexes based on P(III) acid esters,{[(RE)3PCuBr] (where E = O, N, S); R = n‐Pr, i‐Pr, Et2N} were obtained and characterized using IR, 31P NMR spectroscopy, and single crystal X‐ray diffraction. The comparative structural characteristics of complexes with various donor atoms (E = O, N, S) are analyzed. © 2008 Wiley Periodicals, Inc.

Comparison of crystal structure and DFT calculation of triferrocenyl trithiophosphite’s conformation

“…gauche-configuration of alkyl(aryl)thio groups has been observed for free trithiophosphites even in solid state [7] or in gas phase [8][9][10].…”

“…The use of ferrocene derivatives containing a phosphorus-sulfur bond is a promising direction, since coordination with a metal atom can occur both at the phosphorus and sulfur atoms [7]. To obtain such complexes it is important to know the conformational capabilities of the ligand [8][9][10][11].…”

Comparison of crystal structure and DFT calculations of triferrocenyl trithiophosphite’s conformance

“…For triferrocenyl trithiophosphite a trans-gauche-gauche configuration with torsion angles of −34°, −40°, and 173°, respectively, has been observed, although a propeller-like gauchegauche-gauche configuration of alkyl(aryl)thio groups has been observed for trithiophosphites even in the solid state [7] or in the gas phase [8][9][10].…”

Synthesis and Some Properties of Transition Metal Complexes Based on the Octathiophophetane Ammonium Salts

“…Because of the disproportionate transformations of ligands ranging from the monodentate type of coordination via the P atom to the bidentate type via P and S atoms in one molecule as well as via S atoms only, different types of structure and coordination modes were found in complexes with Cu(I) halides . Therefore, ammonium salts of cyclic octathiotetraphosphetanes represent such type of novel heterocyclic ligands.…”
