Covalent radii revisited.
A new set of covalent atomic radii has been deduced from crystallographic data for most of the elements with atomic numbers up to 96. The proposed radii show a well behaved periodic dependence thatExpand

TLDR
The analysis of more than five million interatomic "non-bonded" distances has led to the proposal of a consistent set of van der Waals radii for most naturally occurring elements, and its applicability to other element pairs has been tested. Expand
Continuous symmetry maps and shape classification. The case of six-coordinated metal compounds
A continuous symmetry study of the structures of transition metal six-vertex polyhedra is presented, considering both molecular models and experimental structural data. The concept of symmetry map isExpand
The rich stereochemistry of eight-vertex polyhedra: a continuous shape measures study.
TLDR
Reference polyhedra, shape maps, and minimal-distortion interconversion paths are presented for eight-vertex polyhedral and polygonal structures within the CShM framework, and structural classification is shown to be greatly facilitated by these tools. Expand
Continuous Shape Measures as a Stereochemical Tool in Organometallic Chemistry
The continuous shape measures of homoleptic organometallic compounds of the transition elements relative to the classical coordination polyhedra offer a tool for their accurate stereochemicalExpand
Shape maps and polyhedral interconversion paths in transition metal chemistry
A systematic study of the stereochemistry of the coordination sphere of transition metal compounds has been carried out recently from the point of view of the continuous shape measures (CShM). InExpand
Minimal distortion pathways in polyhedral rearrangements.
TLDR
Several commonly used polytopal rearrangement pathways are shown to be in fact minimum distortion pathways: the spread path leading from the tetrahedron to the square, the Berry pseudorotation that interconverts a square pyramid and a trigonal bipyramid, and the Bailar twist for the interconversion of the octahedron and the trigonal prism.

Distortions in octahedrally coordinated d0 transition metal oxides : A continuous symmetry measures approach
More than 750 d0 transition metal oxide octahedra have been examined in order to better understand the out-of-center distortion occurring with these cations. A continuous symmetry measures approachExpand
Structure and stability of the X3- systems (X = fluoride, chloride, bromide, iodide) and their interaction with cations
The molecular and electronic structure of the trihalide anions as well as their relative stability toward dissociation into a halogen molecule and a halide ion has been studied by full ab initio andExpand
