Reaction between Re2(OAc)4Cl2 and N,N′-dicyclohexylbenzamidine (HDCyBA) under molten conditions yielded Re2(DCyBA)2Cl4 (1); reaction of [Bu4N]2[Re2Cl8] with N,N′-di(3-methoxyphenyl)formamidine (HDmAniF) resulted in Re2(DmAniF)2Cl4 (2); reaction of cis-Re2(OAc)2Cl4 with HDmAniF under reflux conditions resulted in cis-Re2(OAc)2(DmAniF)2Cl2 (3). Reaction between Re2(OAc)4Cl2 and α,α,α′,α′-tetramethyl-1,3-benzenedipropionic acid (H2esp) under reflux conditions led to Re2(esp)2Cl2 (4). Crystallographic studies of compounds 1-4 revealed Re-Re bond lengths of 2.1679(6), 2.1804(5), 2.2468(7), and 2.2304(6) A?, respectively, which are consistent with the presence of Re-Re quadruple bond. Also reported are electrochemical properties of compounds 1-4.
