Spectroscopic titration of [Re4(µ3-H)4(CO)12] with chloride ions. An electron-precise tetranuclear cluster as intermediate in the transformation of a tetranuclear unsaturated cluster into trinuclear unsaturated anions
Abstract
The unsaturated tetrahedral cluster [Re4(µ3-H)4(CO)12] easily added halide ions giving [Re4H4X(CO)12]– anions, which in the presence of even poor donor species underwent fragmentation to unsaturated triangular cluster anions.
