Reaction of halfsandwich iridium polychalcogenide complexes with dimethyl acetylenedicarboxylate. Molecular structure of Cp*Ir[S2C2(COOMe)2]

Synthesis and characterization of half-sandwich Ir and Ru complexes containing Mnt ligand (Mnt=maleonitriledithiolate)

“…2.375 Å ) [14], but comparable with the corresponding Ir-S bond distances in the 16-electron complexes Cp * Ir[S 2 C 2 (COOMe) 2 ] (av. 2.233 Å ) [15], Cp * Ir[C 2 S 2 (B 10 H 10 )] (av. 2.263 Å ) [13] and Cp * Ir(S 2 C 6 H 4 ) (av.…”

Formations and structures of cobalt dithiolene complexes with nitrogen group-substituted cyclopentadienyl ligands

“…The dihedral angles between the cobaltadithiolene and Cp planes are almost right angles (87.369 (4), 92.654 (5), 95.038 (6) and 90.713 (7) in Table 1). Namely, these complexes have typical two-legged pianostool geometries identical to those of the 16-electron CpCo III [15], CpRh III [16] and CpIr III [17] dithiolene complexes. In other cases, (g 6 -arene)Ru II [18] and CpNi III (5).…”

Halfsandwich Complexes Containing the Tetrathiotungstate Chelate Ligand. Crystal and Molecular Structure of Cp*Rh(PMe3)[(μ‐S)2WS2] (Cp* = η5‐Pentamethylcyclopentadienyl)

“…We have earlier described η 5 -pentamethylcyclopentadienyl halfsandwich iridium cyclo-oligosulfido complexes, Cp*-Ir(PMe 3 )(S n ) (n ϭ 4, 5, 6) [1], which react with dimethyl acetylenedicarboxylate to give Cp*Ir(PMe 3 )[S 2 C 2 -(COOMe) 2 ] [2] and then the thiolenes, Cp*-Ir[S 2 C 2 (COOMe) 2 ] [2], cf. [3].…”

“…Related rhodium compounds are also accessible [4], analogous to the known series CpRh(PPh 3 )(S n ) (n ϭ 4, 5, 6) [5]. In this context, we have prepared Cp*Rh and Cp*Ir complexes containing the tetrathiotungstate ligand, [WS 4 2Ϫ ], and determined the molecular structure of Cp*Rh(PMe 3 )[(µ-S) 2 WS 2 ].…”
