What is Synthesis and Spectroscopic Characterisation of Binuclear Molybdenum-rhenium Complexes about?

Abstraet--Protonation of CpMo(q3-C3Hs)(CO)2 followed by reactions with several diazole ligands produce the molybdenum half-sandwich complexes [CpMo(CO)2L2] ÷ (L2 = Bisimidazole (H2Biim), pyrazole (Hpz)2, Cpz4, and [Bpz4] ) in good yields. Deprotonation of [CpMo(CO)2(H2Biim)] + gives the anionic complex [CpMo(CO)2(Biim)]-. The structure of [CpMo(CO)2(H2Biim)][ReO4] was determined by X-ray single crystal analysis. The coordination geometry around the molybdenum atom in the complex cation [CpMo(CO)2(H2Biim)] + can be described as a distorted square pyramid. The basal plane is defined by two nitrogen atoms of H2Biim bidentate ligand and two carbon atoms of carbonyl groups. The apical position is occupied by five carbon atoms of the qs-CsH 5 ligand. The Mo centre lies at 0.94(1)/k from the basal plane in the apical direction. [CpMo(CO)2(Biim)]-reacts with CIReO3 or MeReO3 (MTO) to give binuclear complexes of the formula [{CpMo(CO)2}(#-Biim){Re(X)O3}]Na (X = CI, CH3) in quantitative yields. [CpMo(CO)z(/~-fpz4)][BF4] reacts with C1ReO3 to yield [{CpMo(CO)z}(gt-Cpz4){Re(CI)O3}][BF4]. The corresponding adduct [{CpMo(CO)z}~-Cpz4){Re(C1)O3}][BF4] can not be obtained in a pure form.
