摘要：

An attempted synthesis of [Re(CO3)(mu3-OH)]4, 1, by reacting Re2(CO)10 with an excess of NMe3O in THF resulted instead in isolation of a disproportionation product, [fac-Re(CO)3(ONMe3)3][ReO4], 2. The structure of 2 was determined via X-ray crystallography: triclinic, P1BAR, a = 9.499(5), b = 9.841(2), c = 13.448(2)angstrom, alpha = 109.92(2), beta = 106.89(3), gamma = 93.15(4)-degrees, D(calc) = 2.22 g cm-3 and Z = 2. Least-squares refinement based on 1606 observed (I > 3sigma(I)) reflections gave final values of R = 0.040 and R(w) = 0.047. The cation is a distorted octahedron that exhibits several structural manifestations of steric crowding among the bulky NMe3O ligands.
