Publikováno v: Chemistry (Weinheim an Der Bergstrasse, Germany)

Homoleptic Group 4 metal carbonyl cation and neutral complexes were prepared in the gas phase and/or in solid neon matrix. Infrared spectroscopy studies reveal that both zirconium and hafnium form eight‐coordinate carbonyl neutral and cation comple

Transition‐Metal Chemistry of Alkaline‐Earth Elements: The Trisbenzene Complexes M(Bz) 3 (M=Sr, Ba)

Autor: Sudip Pan, Mingfei Zhou, Qian Wang, Jian‐Hong Bian, Guohai Deng, Guanjun Wang, Gernot Frenking, Yan-Bo Wu, Lili Zhao

Publikováno v: Angewandte Chemie (International Ed. in English)

We report the synthesis and spectroscopic identification of the trisbenzene complexes of strontium and barium M(Bz)3 (M=Sr, Ba) in low‐temperature Ne matrix. Both complexes are characterized by a D 3 symmetric structure involving three equivalent �

K(CO) 8 − and Rb(CO) 8 − : Cube-Like Alkali Octacarbonyls Satisfying the 18-Electron Rule

Autor: Yuan-Yuan Ma, Xiao-Qin Lu, Si-Dian Li, Yue-Wen Mu, Hai-Gang Lu, Hai-Ru Li, Yan-Bo Wu

Publikováno v: Journal of Cluster Science. 30:621-626

Inspired by recent discoveries of alkaline-earth octacarbonyls and based on extensive first-principles theory investigations, we predict herein the possibility of perfect cube-like alkali octacarbonyls M(CO) 8 − (Oh, 3A1g) (1) (M = K, Rb) which sat

Electron-counting in intermetallics made easy: the 18-n rule and isolobal bonds across the Os–Al system

Autor: Daniel C. Fredrickson, Vincent J. Yannello, Ken Miyazaki

Publikováno v: Zeitschrift für Kristallographie - Crystalline Materials. 232:487-496

Electron count is one of the key factors controlling the formation of complex intermetallic structures. The delocalized nature of bonding in metals, however, has made it difficult to connect these electron counts to the various structural features th

Ligand stabilization of manganocene dianions - in defiance of the 18-electron rule

Autor: Santanab Giri, Hong Fang, Puru Jena, Monalisa Yadav

Publikováno v: Physical chemistry chemical physics : PCCP. 21(44)

Manganocene [Mn(C5H5)2], a 17-electron system, is expected to have a high electron affinity, as addition of an extra electron would make it a closed-shell 18-electron system. Surprisingly, it has a very low electron affinity of only 0.28 eV. Combined

Structure and bonding in binuclear metal carbonyls. Classical paradigms vs. insights from modern theoretical calculations

Autor: Robert Ponec

Publikováno v: Computational and Theoretical Chemistry. 1053:195-213

The nature of the bonding interactions in a series of bridged and unbridged binuclear metal carbonyls has been analyzed using the visual insights provided by the analysis of domain averaged Fermi holes (DAFH). Picture of the bonding emerging from thi
