“…For most of the structural parameters, a linear dependence with the size of the chalcogen or the size of the metal is observed along the series [M(L S )(PPh 3 )] – [M(L Se )(PPh 3 )] – [M(L Te )(PPh 3 )]. The Pd1–Te1 and Pt1–Te1 bonds of 2.4825(2) and 2.502(1) Å are similar to the shortest bond lengths reported in previous studies of palladium [ 21,25–29,34,36–38 ] and platinum [ 39–52 ] phenyltellurolato complexes. Remarkably and probably as a result of the strain in the five‐membered Te1–Ni1–N1 chelate ring, the Ni1–Te1 bond length in [Ni(L Te )(PPh 3 )] is only 2.4050(5) Å.…”

The salicylidene Schiff bases of bis(2-aminophenyl)diselenide and-ditelluride react with [M II Cl 2 (PPh 3) 2 ] (M = Ni, Pt) or [Pd II (OAc) 2 (PPh 3) 2 ] with formation of square-planar complexes with the general formulae [M II (L Y)(PPh 3)] (M = Ni, Pd, Pt, Y = Se, Te). The ligands coordinate to the metals as tridentate {O,N,Se/Te} chelates. The reduction of the dichalcogenides and the formation of the chalcogenolato ligands occurs in situ by released PPh 3 ligands. A mechanism for such reactions has been [a

“…The assigned intermediate (6‐Ph 2 P‐Ace‐5‐)TeFe(CO) 2 Cp ( 4 ) shows a 31 P NMR ([D 8 ]THF) chemical shift ( δ = –24.6 ppm) closer to the starting material 1 ( δ = –32.2 ppm) as in both compounds the Fe–P coordination is lacking. The IR spectrum of 3 reveals CO stretching vibrations at 1918 cm –1 , respectively, which is in good agreement with [PhTeFe(CO)Cp] 2 (1913, 1895 cm –1 ) and PhTeFe(CO)(PPh 3 )Cp (1922 cm –1 ).…”

The reduction of the previously known [(6‐Ph2P‐Ace‐5‐)Te]Cl with K‐selectride (K[sec‐Bu3BH]) provided the title compound (6‐Ph2P‐Ace‐5‐)2Te2 (1). The oxidation of 1 under aerobic conditions afforded the related (6‐Ph2P(O)‐Ace‐5‐)2Te2 (2). Alternatively, 2 was prepared by reduction of the previously known 6‐Ph2P(O)‐Ace‐5‐TeCl with K‐selectride. The reaction of 1 with [Cp(CO)2Fe]2 proceeded with cleavage of the Te–Te and Fe–Fe bonds with elimination of CO and gave rise to a racemic mixture of (6‐Ph2P‐Ace‐5‐)TeFe(CO)Cp (3), which contains pseudo‐tetrahedral Fe atoms in a chiral environment. Upon crystallization, the racemate most likely undergoes spontaneous resolution into a conglomerate of enantiopure crystals.

“…This may mainly be due to the inherent instability of the precursor molecules. Only a few compounds containing Re−Se and Re−Te bonds have been crystallographically characterized and the majority of them contain rhenium in low oxidation states, [12,17–33] where phenylselenolates or ‐tellurolates act as bridging ligands between two tricarbonylrhenium(I) fragments [21–33] . Reports about well‐defined rhenium(III) or rhenium(V) complexes containing arylselenolato or ‐tellurolato ligands are even more rare.…”

In situ prepared lithium arylselenolates {LiSePh, LiSe(2,6-Me 2 Ph), LiSe(2,4,6-Me 3 Ph)} or -tellurolates {LiTePh, LiTe(2,6-Me 2 Ph), LiTe(2,4,6-Me 3 Ph)} react with [ReOCl 3 (PPh 3 ) 2 ] and (NBu 4 )Br in good yields under formation of rhenium(V) complexes of the composition (NBu 4 )[ReO(L) 4 )]. The first oxidorhenium(V) complex with four monodentate phenolato ligands, [ReO(2,6-Me 2 Ph) 4 ] À , was prepared and isolated in crystalline form. This allows a comparison of experimental and computational data of a full series of such compounds with basal O, S, Se and Te donor atoms. Similar reactions with [ReCl 3 (PPh 3 ) 2 (CH 3 CN)] or [ReCl 3 (PMe 2 Ph) 3 ] give trigonal bipyramidal rhenium(III) complexes of the compositions [Re(PPh 3 )(L) 3 (CH 3 CN)] or [Re-(PPh 3 ) 2 (L) 3 ] depending on the chalcogenolate applied. The reported oxidorhenium(V) and rhenium(III) complexes were fully characterized by spectroscopic methods and X-ray diffraction. The bonding situation in the rhenium(V) and rhenium(III) chalcogenolates was assessed through density functional theory calculations based on the quantum theory of atoms in molecules (QTAIM), natural bonding orbital (NBO) analysis, charge analysis, the electron localization function (ELF) maps and topological descriptors at the {3,À 1} critical points such as metallicities. Expectedly, the ionicity of the rhenium-chalcogen bonds decreases according to all three applied charge models from O to Te. Generally, the ReÀ Se and ReÀ Te bonds are more directional in the Re(III) complexes than in the oxidorhenium(V) compounds.
