Monocapped trigonal prism

Hirschinger et al. used NMR to show that the biphasic domain seen on chemical lithiation of V2O5 at high temperatures to form lithiated /3 ( Li NMR resonance at —27 ppm due to monocapped trigonal prisms) and ji (—M ppm tetrahedral site) phases should be extended from x = 0.33 to 0.48 (at 600 °C).155,156 unpaired electrons become increasingly...

The sodium salt Na5Zr2Fi3 contains [Zr2F13]5 anions of symmetry in which two ZrF7 monocapped trigonal prisms share the F atom that occupies the capping site (Zr—F terminal = 2.00-2.10, Zr—F bridging = 2.10 A).546... 

In the case of the stoichiometries M M2X7, structures tend not towards more highly condensed MX6 octahedra but towards seven-coordinated metal ions, as in KM2C17 (M = Gd-Tm or Y), where monocapped trigonal prisms are interconnected to form layers, and in M M2C17 (M = Rb, M = Sm-Yb or Y M = Cs, M = La or Pr) where the lanthanide ions are seven- and eight-coordinated.522...

The sulfur atoms create bicapped trigonal prismatic arrangement around the Tbl, Tb2, and Tb3 atoms. Monocapped trigonal prism occurs only around the Tb4 atoms. The shortest Tb-S distance is 0.2692 ran. The silicon atom is located in a tetrahedron formed by the S atoms. The shortest Si-S distance is 0.2059 nm. The SI, S3, S6, SIO, and Sll atoms have triangular surroimdings formed by 2Tb and ISi atoms. All other independent sulfur atoms have tetrahedral coordination spheres. Several of them, that is the S2, S4, S5, S7, and S8 atoms are located outside their respective tetrahedra. Each CP of the sulfur atom is formed by 3Tb and ISi atoms. 

Structure type LaCuPbSa (Brermarr arrd Ibers, 1992) (Figure 103, Table 53). SG Pnma, Z = A, a = 0.8091, b = 0.4093, c = 1.5996 nm. The rarrdomly distributed La and Pb atoms (M) are located in monocapped trigonal prisms formed by the S atoms. The shortest M-S distance is 0.2864 run. The sulfur atoms create a tetrahedral arrangement around the single independent copper atom, and the shortest Cu-S distance is 0.2334 run.
