A tetranuclear calcium hydride cluster with a highly symmetric [Ca4H6](2+) core
Abstract
A highly symmetric, dicationic tetranuclear calcium hydride cluster with an adamantoid [Ca4H6](2+) core stabilized by the NNN macrocycle Me(3)TACN (1,4,7-trimethyl-1,4,7-triazacyclononane) was prepared. DFT calculations indicate delocalized bonding within the [Ca4H6](2+) fragment with d-orbital contribution.
