The synthesis and crystal structures of the first examples of six-membered inorganic iridacycles containing the [(Ph2PE)2N]− ligand (E=S or Se)

Synthesis and characterization of half-sandwich iridium(III) and rhodium(III) complexes bearing organochalcogen ligands

“…1, the complex 1a has a three-legged piano-stool geometry and coordinatively saturated metal centers with an eightmembered macrocyclic ring. The iridium-sulfur bond distance (Ir(1)-S(1)) is 2.3862(14) Å, which is compatible with a typical single bond length between the iridium center and the sulfur atom reported in the previous literature [28][29][30][31], but longer than that in the complexes with five-membered metalladithiolene ring complexes [32][33][34][35]. The structure of 1a is solved in the orthorhombic space group pnma with high asymmetric, while the selenium analog complexes [Cp * Ir(Mbis)Cl]Cl [13] adopt triclinic crystal system and P 1 space group, but the structures of these two complexes are very similar to each other.…”

Synthesis and Characterization of HN(SPiPr2)(SePPh2) and [Te{N(SPiPr2)(SePPh2)}2]

“…A number of bis-S or bis-Se compounds HN(QPR 2 ) 2 (Q = S, Se; R = Me, Et, Ph, i Pr, n Bu, OPh) have been synthesized, and the coordination chemistry of their anions [N(QPR 2 ) 2 ] - has been extensively studied with a variety of transition-metal, main-group, and rare-earth systems. − In addition, the unsymmetrical bis-S compounds HN(SPR 2 )(SPR‘ 2 ) (R = Ph, R‘ = Me, Et, i Pr, OEt, OPh; R = OPh, R‘ = Et, i Pr, OEt) have been prepared and their anions complexed with Co, Zn, Pd, and Pt systems. − …”

Synthesis and Single-crystal Characterization of the Square Planar Complex [Ni{(SPPh2)2 N−S,S‘}2]·2THF

“…There have been numerous studies of the coordination chemistry of the tetra(alkyl,aryl)dithioimidodiphosphinate anion [N(SPR 2 ) 2 ] -, which acts as a bidentate ligand that is able to form inorganic (carbon-free) chelate rings. [1][2][3][4][5] The interest in this type of ligand is due mainly to the high flexibility of the SPNPS system and the large S‚‚‚‚S bite (ca. 4 Å).…”
