Complexes of Ni(II) with sterically-hindered thiolate ligands. Crystal structures of complexes with the [NiS2N2], [NiS2P2] and [NiS2O2] cores

Synthesis and Structural Characterization of Cobalt, Nickel and Copper Phosphanylthiolato Complexes

“…The Ni–S bond lengths, 2.1647(8) and 2.1753(8) Å, are similar and are analogous to those found in [Ni(Ph 2 PC 6 H 4 S‐2) 2 ]21 [2.151(3) Å] and [Ni{Ph 2 PC 6 H 3 S‐2(Me 3 Si‐6)} 2 ]4 [2.180(1) Å]. These values fall within the range 2.149–2.179 Å usually found in square planar nickel complexes with chelating ligands that contain sulfur donor atoms.…”

“…The Ni–S(terminal) bond lengths, which involve sulfur atoms from the chelate rings, are slightly shorter [2.156(2)–2.156(2) Å] than those for Ni–S (bridge) distances, in the range 2.197(2)–2.236(2) Å, as in the case in other systems with terminal and bridging sulfur atoms 20. The Ni–P bond lengths [2.110(2) and 2.105(2) Å], although within the expected range, are at the lower end of the range found in complexes that contain this type of ligand 4,21…”

Synthesis and characterisation of cobalt(III), nickel(II), copper(I) and silver(I) complexes of silylated pyridine-2-thione

“…These results are very similar to those found for [Ni(3-Me 3 SipyS) 2 ], for which a square planar structure has been confirmed by X-ray diffraction. 34 The magnetic moments of the mixed nickel() complexes lie in the range 2.95-3.18 µ B at room temperature. These values are of the order expected for octahedral nickel() complexes.…”

Electrochemical syntheses and structures of lead(II) and bismuth(III) complexes of 4-(trimethylammonio)benzenethiolate

“…Being aware of the fact that the electrochemical oxidation of sacrificial anodes have been proved an effective route to prepare different kinds of metal complexes [17][18][19][20][21][22] and as our continuing efforts to expand the family of metal/ Tab complexes, we carried out the electrochemical syntheses of Tab complexes with Pb or Bi (as sacrificial anodes) in MeCN containing Tab and Et 4 NClO 4 , and two Pb(Tab) 3 -(ClO 4 ) 2 (1) and Bi(Tab) 3 (ClO 4 ) 3 (2) were isolated therefrom. In this paper, we report their syntheses, crystal structures and electrochemical properties.…”
