micro-Oxo-bis{{2,2'-[2,2-dimethylpropane-1,3-diylbis(nitrilomethylidyne)]diphenolato}oxorhenium(V)}
The title compound, [Re(2)O(3)(C(19)H(20)N(2)O(2))(2)], is a hexacoordinate complex containing an [Re(2)O(3)](4+) core with a linear O=Re-O-Re=O bridge. The distorted octahedral coordination of the Re(V) atom is achieved by an N(2)O(2) donor set from the tetradentate imine-phenol ligand. The overall charge of the compound is neutral due to deprotonation of the phenol groups, and the terminating and bridging O atoms. The Re=O and Re-O bond distances of the [Re(2)O(3)](4+) core are 1.699 (4) and 1.911 (1) A, respectively. The Re-O and Re-N bond distances of the equatorial plane are in the ranges 2.024 (4)-2.013 (4) and 2.128 (5)-2.120 (5) A, respectively.
