The rhenium diisocyanide complex fac-[Re(O)Cl3(CNC6H3-(CH3)2-2,6)2] (1) was obtained by reaction of mer-[Re(O)Cl3(SMe2)-(OPPh3)] with 2 equiv. of the ligand 2,6-dimethylphenylisocyanide. In the presence of water complex 1 reacts under HCl evolution to yield [(2,6-(CH3)2-C6H3NC)2Cl2(O)ReORe(O)Cl2(CNC6H3-(CH3)2-2,6)2] (2). The dinuclear complex 2 was shown by X-ray crystallography to contain an almost linear OReOReO core. Crystals of 2, C36H36Cl4N4O3Re2, are orthorhombic, space group Pccn (No. 56) with a = 11.169(9), b = 13.761(4), c = 25.831(6)Å, Z = 4 and Dc = 1.818g cm−3.
