Ca-Ca interaction in inverse sandwich Ca-C8H8-Ca

12 November, 2014 - 01:17

Dalton Trans., 2015, Advance Article
DOI: 10.1039/C4DT02282C, PaperNan-nan Liu, Si-meng Gao, Yi-hong Ding
The inverse sandwich Ca-C8H8-Ca is predicted to be open-shell singlet Ca-C8H8-Ca. The singlet diradical character is caused by the C8H8 ligand preventing the spin-paired electrons of different calcium atoms from forming Ca-Ca bonds. A direct Ca-Ca bond is favorable in closed-shell singlet (DME)3Ca-C8H8-Ca(DME)3, because dimethyl ether molecules could push the spin-paired electrons of different calcium atoms to migrate towards the direction of Ca-Ca bonding.
