Cuboctahedral copper cluster promotes main group coordination to new high
First examples of compounds in which a sulfide, chloride or bromide ion holds so large a coordination number
A team of scientists from Taiwan and France has synthesised a series of inverse-coordination clusters from a new copper-centred cuboctahedral arrangement. The precursor is the first copper-centred cluster to show cuboctahedral geometry, and can be further reacted to give sulfur, bromine or chlorine inverse-coordination clusters with the highest coordination number ever observed.
