Crystal structure of the hexagonal (Zn, Mg)4Ho and (Zn, Mg)4Er

open access: yesJournal of Alloys and Compounds, 2006
The crystal structure of the hexagonal (Zn, Mg)(4)Ho/Er was determined by single crystal X-ray diffraction analysis. For the Zn68.4Mg12.7Ho18.9, the structural model, refined to a final R-value of 0.0672, has the composition of Zn69.34Mg12.01Ho18.65, a =

Nonspherical Deltahedra in Low-Energy Dicarbalane Structures Testing the Wade–Mingos Rules: The Regular Icosahedron Is Not Favored for the 12-Vertex Dicarbalane

open access: yesInorganic Chemistry, 2015
Theoretical studies on the dicarbalanes C2Aln–2Men (n = 7–14; Me = methyl) predict both carbon atoms to be located at degree 4 vertices of a central C2Aln–2 deltahedron in the lowest energy structures.

Orthogonal layouts using the Deltahedron heuristic [PDF]

open access: possibleAustralas. J Comb., 1995
Summary: The Deltrahedron heuristic has been demonstrably effective for generating highly-weighted maximal planar adjacency graphs for use in facilities layout problems. In this paper, we present a linear-time algorithm for constructing an orthogonal block plan dual to such an adjacency graph which guarantees that all prescribed adjacencies are ...
