By reaction of (n-Bu4N)2[ReBr6] with pyridine and (n-Bu4N)BH4 in dichloromethane various bromo-pyridine-rhenium(III) complexes are formed which can be separated by chromatography. Electrochemical oxidation of (n-Bu4N)2[ReBr5Py] leads to (n-Bu4N)[ReBr5Py]. X-ray structure determination on a single crystal has been performed of (n-Bu4N)[ReBr5Py] (monoclinic, space group P21/n a = 11,248(5), b = 17,192(5), c = 15,206(5) Å, β = 97,600(5)°, Z = 4).

Abstract The molecular structure of the bridged [1]-titanocenophane 1,1'-dimethylsilylene titanocene dichloride, (CH3)2Si(C5H4)2TiCl2, has been investigated by an X-ray structure determination.

The crystal structure of [Cu(sac)2(nic)2(H2O)] (sac = saccharinate anion; nic = nicotinamide) has been determined by single-crystal X-ray diffraction. It crystallizes in the monoclinic space group C2/c with Z = 4 and the Cu(II) ion presents a CuN4O square pyramidal coordination. Some comparisons with related structures are made and the most important features of its IR spectrum were also discussed.
