title: Tetra-kis[μ-N,N'-bis-(4-bromo-phen-yl)formamidinato-κN:N']dimolyb-denum(II) tetra-hydro-furan solvate.
abstract: The title complex, [Mo(2)(C(13)H(9)N(2)Br(2))(4)]·C(4)H(8)O, contains a quadruply bonded Mo(2) (4+) unit equatorially coordinated by four N,N'-bis-(4-bromo-phen-yl)formamidinate ligands, forming a dimetal paddlewheel complex. The centroid of the Mo-Mo bond is located on a special position with 2/m symmetry. In the crystal, complex mol-ecules are linked by Br⋯Br inter-actions [3.7049 (10) Å]. The disordered solvent mol-ecule could not be satisfactorily modelled and was therefore eliminated from the final refinement.
