On the basis of the preceding correlation, the C2 bond was found about 15?kcal/mol weaker than that of acetylene, with a 25% σ participation; the bond order of C2 can be evaluated at about 2.8 if we assume bond orders of 3 for acetylene and 2 for ethylene. Some sila homologs of ...
Bonding in the ground state of C is still a matter of controversy, as reasonable arguments may be made for a dicarbon bond order of , , or . Here we report on photoelectron spectra of the C anion, measured at a range of wavelengths using a high-resolution photoelectron imaging spectrometer...

In the crystal structure of a 5-ferrocenyl-4-carbaldehyde-1,2,3-triselenole (SENCIZ) within a five membered C2Se3 ring, both carbon atoms and the Se(1) and Se(3) atoms are almost coplanar (torsion angle Se(1)–C(2)–C(3)–Se(3) = 3.8°), whereas due to lone pair-lone pai...

Here it is shown that the former representation, the natural orbital representation, accounts nicely for the quadrupole bond character of the ground states of C2, BN, CB(-), and CN(+), and for the double bond order character of the isovalent (1)Σg (+) state of Si2. Similarly, the...
