A rarely encountered class of stable mononuclear 17-electron rhenium(II) complexes: Trans-[Re(CNR)2(NCCH3)L(PPh3) 2](BF4)2 (R = i-Pr or t-Bu and L = CH3CN or py)

The reactions of [ReH(NCCH3)3L(PPh3)2](BF 4)2 (L = CH3CN, py, C6H11NH2, or t-BuNH2) with RNC (R = i-Pr or t-Bu) proceed in a stepwise fashion to afford [ReH(NCCH3)2(CNR)L(PPh3)2](BF 4)2 (I), [Re(CNR)2(NCCH3)L(PPh3)2]BF 4 (II), and [Re(CNR)4(PPh3)2]BF4 (III). Complexes of the type II are oxidized to the corresponding paramagnetic 17-electron dications. The crystal structure of the dichloromethane solvate of [Re(CN-t-Bu)2(NCCH3)2(PPh3) 2] (BF4)2 shows it to be the all-trans isomer. It crystallizes in a unit cell with a = 44.729 (2) ?, b = 12.170 (1) ?, c = 21.018 (2) ?, β = 106.15 (2)°, V = 10.989 ?3, Z = 8, and monoclinic space group C2/c.
