Abstract
Reaction of [n-Bu 4 N] 2 [Re 4 (CO) 16 ] with AgBF 4 in acetonitrile affords the compound [(CH 3 CN) 3 Re(CO) 3 ][BF 4 ]. The latter crystallizes in monoclinic space group P2 1 /c with unit cell dimensions a = 11.021(5) Å, b = 11.136(5) Å, c = 12.980(6) Å, β = 96.906(25)°, and four molecules per unit cell. Data were collected by counter methods and the structure was refined using least-squares procedures to give R = 0.041. The rhenium cation is approximately octahedrally coordinated by six facially arranged ligands. The mean rhenium–nitrogen distance is 2.13 Å, and the mean rhenium–nitrogen–carbon angle in the coordinated acetonitrile is 174.7°.
