Synthesis and characterisation of the chloride-bridged copper–ruthenium cluster dianion [{Ru6Cu2C(CO)16}2Cl2]2–
Abstract
The mixed-metal ruthenium–copper cluster dianion [{Ru6Cu2C(CO)16}2]2–1 has been synthesised in quantitative yield from [Ru6C(CO)16]2– and CuCl; the crystal structure of the [N(PPh3)2]+ salt shows that the two Ru6 octahedra are linked by a rectangular planar arrangement of copper atoms two opposite edges of which are bridged by chlorine atoms.
