The neopentylidene ligand (W=C(1) = 1.986 (21) ) and the oxo ligand (W=O = 1.697 (15) ) are mutually cis, with an interligand angle of O=W=C(1) = 102.0 (9)°. The geometry of this octahedral W(=O)-(=CHCMe3)(PMe3)2Cl2 molecule is compared to that of the trigonal-...
2, 3, 4 RPP series according to the simulation models. The relative tilt (blue rectangles) is defined as the difference in tilt angle between monolayer and bulk octahedral tilt angle.cThe distance of two apical I atoms

The ideal coordination polyhedron may be described by the twist angle, θ, between opposite triangular faces where θ =0° for a trigonal prism and θ = 60° for an octahedron. Calculations of ligand-ligand repulsions predict small values of θ for ligands with a small "bite", b, and ...
For Zn2+, Cu2+, Ni2+, and Co2+ the central metal atom of the linear trimetallic [M-3(L1O)(4)](2+) unit is four coordinate and has a pseudotetrahedral geometry with a dihedral angle, omega, between the two McentralO2Mterminal planes of 79.9 degrees (Zn), 61.2 degrees (Co), ...
The resulting imbalance in S-S bonding leads to an opening up of the S-Mc-S angle. The cyclic voltammogram shows two quasireversible redox events between -1.0 and +1 .OV, a one-electron reduction at Ell* = -0.17 V, and an oxidation at Ellz = +0.45 V. 'Hand 13CNMR, UV-visible,...
Rare-earth titanates form very fragile liquids that can be made into glasses with useful optical properties. We investigate the atomic structure of 83TiO2-17Nd2O3 glass using pair distribution function (PDF) analysis of X-ray and neutron diffraction with
