A proof of an extension of the icosahedral conjecture of Steiner for generalized deltahedra

open access: yes, 2007
In this note we introduce a new family of convex polyhedra which we call the family of generalized deltahedra or in short, the family of g-deltahedra.

Density functional studies on the hydrogen storage capacity of boranes and alanes based cages

open access: yes, 2012
The hydrogen storage (H-storage) capacity of various boranes and alanes have been investigated using density functional theory (DFT) based M05-2X method employing 6–31+G** basis set.

Hypoelectronic Dirhenaboranes Having Eight to Twelve Vertices: Internal Versus Surface Rhenium–Rhenium Bonding

open access: yes, 2016
Fehlner, Ghosh, and their co-workers have synthesized a series of dirhenaboranes Cp2Re2Bn–2Hn–2 (n = 8, 9, 10, 11, 12) exhibiting unprecedented oblate (flattened) deltahedral structures.

Silylated Ge9 Clusters as New Ligands for Cyclic (Alkyl)amino and Mesoionic Carbene Copper Complexes

open access: yes, 2019
The coordination of Ge9 Zintl clusters at (carbene)­CuI moieties is explored, and the complexes [(CAAC)­Cu]2[η3-Ge9{Si­(TMS)3}2] (1), (CAAC)­Cu­[η3-Ge9{Si­(TMS)3}3] (2), and (MIC)­Cu­[η3-Ge9{Si­(TMS)3}3] (3) are compared with their known N-heterocyclic ...

Manganese-centered ten-vertex germanium clusters: the strong field Ge10 ligand encapsulating a transition metal

open access: yes, 2015
The experimental realization of pentagonal prismatic structures for M@ (M = Co, Fe) containing interstitial transition metal atoms makes of interest the chemistry of corresponding manganese derivatives Mn@.

From closo to isocloso Structures and Beyond in Cobaltaboranes with 9 to 12 Vertices

open access: yes, 2016
Density functional theory (DFT) studies predict the dianions CpCoBn−1Hn−12− (n = 9, 10, 11, 12; Cp = η5-C5H5) to have structures based on the most spherical deltahedra found in the isoelectronic boranes BnHn2−.

Density Functional Study of 8- and 11-Vertex Polyhedral Borane Structures:  Comparison with Bare Germanium Clusters

open access: yes, 2016
Density functional theory (DFT) at the hybrid B3LYP level has been applied to the polyhedral boranes BnHnz (n = 8 and 11, z = −2, −4, and −6) for comparison with isoelectronic germanium clusters Genz.
