The angle between the mean planes of the two phenylene units is 76.3°. The C—N bond lengths in compound 3 suggest partial double bond character for C2—N1 [1.361(3) Å] and C15—N2 [1.374(3) Å], but not for C8—N1 [1.426(3) Å]. This demonstrates the stronger electron ...
This paper reviews the highlights of our recent work in this area. Systems discussed include the following: (1) The systems Cp2Ni2Bn2Hn2 (Cp=畏5-C5H5) and Cp2M2C2Bn4Hn2 (M=Co, Rh, Ir) having 2n+2 Wadean skeletal electrons and exhibiting most spherical closo deltahedral structures; ...

othe triple bond of n2 is therefore composed of these two orbitals and orbital 1.othe bands corresponding to orbitals 2 a 23、nd 5 are narrow; hence these orbitals contribute little to the bonding and may be regarded as the two unshared pairs of n=n. onote that this result is ...
Bonding in the ground state of C2 is still a matter of controversy, as reasonable arguments may be made for a dicarbon bond order of 2, 3, or 4. Here we report on photoelectron spectra of the C2− anion, measured at a range of wavelengths using a high-resolution photoelectron imaging...
