A series of novel cationic methylimidorhenium(V) complexes, trans-(1+) 1, cis-(1+) 2, (1+) 3 and (1+) 4 (py = pyridine) have been synthesized as their perchlorate salts.The crystal structure of 3 has been determined: monoclinic, space group P2₁/c, a = 10.223(4), b = 17.663(2), c = 25.222(3) Angstroem, β = 90.70(2) deg and Z = 4.The structure of 3 revealed an almost linear Re-N-Me geometry, consistent with a four-electron donor fromulation for the methylimido unit.Spectroscopic studies on 1-4 and their nitrido and exo analogues. ClO4 5 and ClO4 6 all show low energy (d_xy) -> (d_R*) electronic absorption bands at 400-500 nm.
