The First Seven-Coordinated Triiodo Complex of Rhenium(III)

The reaction of cis -[ReO 2 I(P Ph 3 ) 2 ] with tert -butyl isocyanide in benzene led to the isolation of the complex [ReI 3 (CN- t -Bu) 3 (P Ph 3 )] ( 1 ). The complex is unusual since it contains bulky ligands with large cone angles, i.e. three iodides, three isocyanides with tert -butyl groups and a triphenylphosphine as ligands in a seven-coordinate geometry around the rhenium(III) metal ion.
