The reactions of cis-Re2(O2CCH3)2Cl 4(py)2 or (n-Bu4N)2Re2Cl8 with PR3 (R = Cy or Ph) in refluxing 1,2-dichloroethane afford the bis-phosphonium salts (R3PCH2CH2PR3)Re2Cl 8; the crystal structure of the derivative where R = Ph shows that this is only the second example of a salt of the [Re2Cl8]2- anion in which a 3-fold orientational disorder of the Re - Re units is encountered. A cation exchange reaction between (Ph3PCH2CH2PPh3)Cl2 and (n-Bu4N)2Os2Cl8 affords (Ph3PCH2CH2PPh3)Os 2Cl8, which possesses an Os - Os bond distance of 2.1896(3) A and is the second example of a crystal structure of a [Os2Cl8]2- salt in which a fully staggered rotational geometry is present.
