Our analysis shows that the 5d\u2010electron configuration of Pt in these compounds is close to (5d)10<\/jats:sup>, and the electrons released from the Li atoms in the Li\/Pt binary compounds are delocalized among the Pt0<\/jats:sup> atoms and Li+<\/jats:sup> ions through the interactions of the Pt 5d orbitals of each Pt with the Pt 6s\/6p of neighboring Pt atoms and the Li 2s\/2p orbitals of neighboring Li atoms. The electron counting schemes best representing the electronic structures of Pt metal, LiPt2<\/jats:sub>, LiPt and Li2<\/jats:sub>Pt are Pt0<\/jats:sup> (d10<\/jats:sup>), Li+<\/jats:sup>[Pt0<\/jats:sup> (d10<\/jats:sup>)]2<\/jats:sub>(e\u2212<\/jats:sup>), Li+<\/jats:sup>[Pt0<\/jats:sup> (d10<\/jats:sup>)](e\u2212<\/jats:sup>), and (Li+<\/jats:sup>)2<\/jats:sub>[Pt0<\/jats:sup> (d10<\/jats:sup>)](2e\u2212<\/jats:sup>), respectively, and hence the Pt atoms of the Li\/Pt binary compounds are predicted to exist as partially negative anions. \u00a9 2008 Wiley Periodicals, Inc.
