on.A 4-center, 6π-conjugated, multiply bonded trigonal-planar complex, [SbCr(CO)53]- (1), was synthesized via the hydride abstraction of [HSbCr(CO)53]2- (1-H) with HBF4·H2O, with the release of high yields of H2. The oxidation state of the Sb atom in [Et4N][1] was well-defined as 0, which was evidenced by X-ray photoelectron spectroscopy and X-ray absorption near-edge structure. The distinct color-structure relationship of this low-valent Sb complex 1 toward a wide range of organic solvents was demonstrated, as interpreted by time-dep
