Bond length and bond order in one of the shortest Cr-Cr bonds.
Multiconfigurational quantum chemical calculations on the R-diimines dichromium compound confirm that the Cr-Cr bond, 1.80 A, is among the shortest Cr(I)-Cr(I) bonds. However, the bond between the two Cr atoms is only a quadruple bond rather than a quintuple bond. The reason why the bond is so short has to be attributed to the strain in the NCCN ligand moieties.
متن کاملWeaker Bonds with Shorter Bond Lengths
One of the paradigms of chemistry predicts that the shorter the bond of a given type is always the stronger bond. Although this qualitatively holds for many compounds, there exists no general proof that this is always correct. Here, we discuss molecules, for which longer bonds lead to stronger rather than weaker bonds. This is possible by introducing the local mode stretching force constants as...
متن کاملTaxable Bond Investing: Bond Funds or Individual Bonds?
Introduction This paper primarily examines the advantages of bond mutual funds over portfolios of directly held bonds for both institutional and individual investors. First, we review the structural advantages of bond mutual funds, which, compared with separately managed and laddered portfolios of individual bonds, generally provide greater diversification; more regular cash flows that promote ...
متن کاملCharacterization of CF bonds with multiple-bond character: bond lengths, stretching force constants, and bond dissociation energies.
Isoelectronic C=F(+) and C=O bonds contained in fluoro-substituted carbenium ions, aldehydes, and ketones are investigated with regard to their bond properties by utilizing the vibrational spectra of these molecules. It is demonstrated that bond dissociation energies (BDEs), bond lengths, vibrational stretching frequencies, and bond densities are not reliable descriptors of the bond strength. T...
متن کاملBond paths are not chemical bonds.
This account takes to task papers that criticize the definition of a bond path as a criterion for the bonding between the atoms it links by mistakenly identifying it with a chemical bond. It is argued that the notion of a chemical bond is too restrictive to account for the physics underlying the broad spectrum of interactions between atoms and molecules that determine the properties of matter. ...
