The complex TpRe(CO)2(THF) (3) (Tp = hydridotris(pyrazolyl)borate) reacts with a variety of aromatic molecules to form stable binuclear complexes of the form {TpRe(CO)2}2(μ-η22‘-L), where L = furan (6), N-methylpyrrole (7), or naphthalene (8). With thiophene, the TpRe(CO)2 fragment yields the sulfur-bound mononuclear complex TpRe(CO)21-thiophene) (5). In the absence of a suitable ligand, complex 3 reacts under a nitrogen atmosphere to form Tp(CO)2Re(μ-N2)Re(CO)2Tp (9). An X-ray diffraction study of a single crystal of 9 provides geometric details.
