The reaction of [Cp#2NbTe2H] (1#; Cp# = Cp* (C5Me5) or Cp(x) (C5Me4Et)) with two equivalents of [Co2(CO)8] gives a series of cobalt carbonyl telluride clusters that contain different types of niobocene carbonyl fragments. At 0 degrees C, [Cp#2NbTe2CO

Metallocenes of Nb and Ta with η2-Se2H, SeH, and Se Ligands – Crystal Structures of [Cp′2Ta(SeH)H2] and [Cp′2Ta(=Se)H·W(CO)5] (Cp′ =tBuC5H4)

The reactions of [Cp#2NbBH4] (1) [Cp# = C5Me5 (Cp*) or C5Me4Et] and [Cp′2TaH3] (Cp′ = tBuC5H4) with elemental selenium give complexes of the general composition [Cp2MSe2H]. These exist in three isomeric forms, A–C, depending on the metal and th

Addition of Cr(CO)5 to the M(η2- S2) moiety of Cp2 M(S2H (Cp′ = tBuC5H4 : M = Ta; CpX = C5Me4Et: M = Nb) and crystal structures of Cp′2TaS2H · [Cr(CO)5]n (n = 1, 2)

Reaction of Cp′2TaS2H (Cp′ = tBuC5H4) or Cp2xNbS2H (Cpx = C5Me4Et) with an excess of Cr(CO)5THF gives the adducts Cp′2TaS2H · Cr(CO)5 1, Cp′2TaS2H · 2Cr(CO)5 2, and Cp2xNbS2H · Cr(CO)5 3 respectively. 1 and 2 are separated by fractional cr

Irradiation of Cp 2 ∗ Nb(η 2 S 2 )H (Cp ∗ = C 5 Me 5 ) 1a in the presence of Fe(CO) 5 gives the CO-free complex [Cp 2 ∗ NbS 2 ] 2 Fe 2a . The core of 2a contains an FeS 4 tetrahedron which is ligated by two niobocene ligands as shown by X-r
