Crystal and Molecular Structure of Bis(1-diphenylphosphinothioyl-3-methylthioureato)nickel(II)

Abstract

The title compound [Ni{(C6H5)2PSNCS-NHCH3}2] was found to crystallize in the monoclinic space group C2/c with a=23.29(1), b=9.457(2), c=16.40(1) Å, β=121.33(8)°, Z=4. The six-membered chelate ring built of five kinds of atoms, Ni, 2S, P, N, and C, was demonstrated.

Tetrahedral and Square Planar Ni[(SPR2)2N]2 complexes, R = Ph & iPr Revisited: Experimental and Theoretical Analysis of Interconversion Pathways, Structural Preferences, and Spin Delocalization

“…Along these lines, previous investigations on the covalency of Ni−S bonds have employed sulfur K-edge X-ray spectroscopic studies on both T d and SP NiS 4 - and NiS 2 N 2 -containing complexes, respectively, but in this case, the ligands employed were of different types. , The findings of our work, combined with earlier investigations, ,, confirm that dichalcogenated (S or Se) imidodiphosphinate types of ligands can afford either T d or SP complexes based either on different R peripheral groups or, simply, on different experimental conditions. The versatile coordinating properties of the ligands employed in this work toward Ni (II) are evident, since the analogous NiS 4 complexes containing six-membered Ni−S−P−N−C−S chelating rings have so far been shown to be exclusively SP. − …”

“…The versatile coordinating properties of the ligands employed in this work toward Ni (II) are evident, since the analogous NiS 4 complexes containing six-membered Ni-S-P-N-C-S chelating rings have so far been shown to be exclusively SP. [87][88][89][90][91][92] Of special importance is the experimental and theoretical evidence, presented herein, for a strong spin-orbit coupling in the paramagnetic T d NiS 4 complexes studied, leading to large ZFS values, which will be a challenge to confirm by appropriate experimental methods as EPR, 34,93,94 MCD, 93 and Far-IR magnetic spectroscopy. 95 Collectively, our work can form the basis of investigating structure-properties relationships in other NiS 4 -containing systems.…”

Various types of metal complexes based on chelating β-diketones and their structural analogues

“…Later on, data on the structure of an analogous nickel complex with N-(diphenylthiophosphoryl)methylthiourea (120, M = Ni) were documented. 183 It should be emphasised that the reaction of platinum(II) chloride with diphenylthiophosphorylthiourea in CH 2 Cl 2 results in complex 121, whose coordination sphere contains bidentate chelating ligands coordinated in either deprotonated (structures 4, 8) or neutral (structure 10) form. The exchange reaction of platinum(II) or zinc(II) chloride with the potassium salt of the ligand gives the usual chelates with square planar (122) and tetrahedral (123) structures, respectively.…”
