Covalently Bonded ∞1[Pt]- Chains in BaPt: Extension of the Zintl—Klemm Concept to Anionic Transition Metals? — BaPt is prepared from a 1:1 mixture of the
elements (Ar, 1223 K, 2 d). The compound crystallizes in the hexagonal space group
P63/mmc with Z = 2 (NiAs-type structure, single crystal XRD). Pt is coordinated linearly by two other Pt atoms, thus forming a chain of homonuclearly bonded Pt. Band
structure calculations and electron localization function analyses indicate a covalent
character of Pt—Pt interactions along the c axis and two-dimensional metallic conductivity parallel to the ab plane. — (KARPOV, A.; NUSS, J.; WEDIG, U.; JANSEN*,
