La2(TlPb)3 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. La is bonded to six Tl and six Pb atoms to form LaTl6Pb6 cuboctahedra that share corners with eight Tl
Pt3As crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pt+0.67+ is bonded in a see-saw-like geometry to four equivalent As2- atoms. There are two shorter (2.79 Å
Biphenylation using (Li(THF)4)2·Zr(biphe)3 of hexabromotriptycenes bearing H (1-H) or Bu (1-Bu) at the bridgeheads gave triptycenes with triphenylene blades. The blades extend both perpendicular and p
