Abstract
The (NC5H2(C6H5)4)2[Re2Cl8] · 2CH3CN compound was prepared by the reaction of (n-Bu4N)2[Re2Cl8] with the 1,2,4,6-tetraphenylpyridinium tosylate in the acetonitrile; it crystallizes upon cooling of the solution at –15°C. The structure consists of the ((C6H5)4C5H2N)+ cation and Re2Cl 2−8 anion with virtual D4h symmetry. The average Re–Re and Re–Cl bond distances are 2.2205 and 2.3431 Å, respectively. In the structure, the Re2Cl 2−8 anions are disordered, such that 71.34% of the Re–Re units are aligned in one direction while 28.66% are aligned orthogonal to it. The principal crystallographic data are as follows: sp. gr. R̅3; a = 26.554(1) Å, c = 23.666(1) Å; V = 14451.6(1) Å3; Z = 9; Dx = 1.643 g cm–3.
