Rhodium(iii) complexes with thiolate and thioether ligands derived from fac(S)-[Rh(aet)3] (aet = 2-aminoethanethiolate): selective formation, characterization and properties

“…[1][2][3][4][5][6] In addition, it has been recognized that the high nucleophilicity of coordinated thiolato groups allows thiolato metal complexes to function as S-donating complex-ligands towards a variety of metal ions to construct S-bridged polynuclear structures. [7][8][9][10][11][12][13][14] To date, the ligating ability of thiolato groups coordinated to cobalt() ion has been extensively investigated, and a large number of S-bridged polynuclear complexes with different nuclearities have been prepared based on mono(thiolato)-, bis(thiolato)-and tris(thiolato)-type cobalt() complexes containing 2-aminoethanethiolate (aet), -cysteinate (-cys), or -penicillaminate (-pen). [11][12][13] On the other hand, reports on the S-bridged polynuclear complexes derived from rhodium() complexes with thiolate ligands are relatively few in number and are limited to polynuclear complexes derived from the tris(thiolato)type fac(S )-[Rh(aet) 3 ] and fac(S )-[Rh(-cys-N,S ) 3 ] 3Ϫ .…”

A reinvestigation of the bonding in bis[(2-mercaptoethyl)salicylidineaminato]oxovanadium(IV)

“…The oxidation peak at 0.65 V is a one-electron-transfer process as shown by the controlled-potential coulometry. When heat was not applied to the reaction mixture, we obtained a pure (6) product as indicated by elemental analysis and also by a cyclic voltammogram that showed the shoulder at 0.45 V to be even smaller.…”

“…The single thiolato group of [(en)2CoL]2+ has been shown to effectively bridge the Co(III) center to Ag(I), Hg(II), Pt(II), Cu(I), and the iodonium ion. [5][6][7] While it has long been assumed that the bridging ability of coordinated thiols allows the facial isomer of CoL3 to function as a tridentate, S-donating ligand to a variety of metal centers (Co(III), Ni(II), Fe(III), Ru(III), Zn(II), Cu(I), Cu(II), and Pb(II)),8'12 none of these [M(CoL3)"]m+adducts have been structurally characterized. The structural analysis presented in this work confirms the two tris(thiolato) bridges originating from the two terminal cobalt(III) ions and the octahedral arrangement of six sulfur atoms about the central cobalt(III) ion.…”

Heterometallic Copper (I) Compounds: Classification and Analysis of Crystallographic and Structural Data

“…Two scalene triangular MoCu 4 subunits span the Cu-Cu edge, forming a heteronuclear "raft" with a centre of symmetry midway along the Cu-Cu edge. The Cu-Cu and CuMo distances of 240.3(1) and 274.5(1,89) pm, respectively, are short enough to be classified as bonding.By contrast, the Cu-Cu and Cu-Co distances of 314 [101],. are too long to be considered bonding.…”
