For n=2 through to n=13, the transition or switch from weak (primarily dipole-dipole-type) intermonomer interactions to a preference for polar covalent bonding occurs within the range 5 doi:10.1002/chem.201502477Kelling J. DonaldWilliam J. KretzOluwarotimi OmorodionChemistry - A European ...
What is the name for the ionic compound K2O? What is the correct name of the compound Cl4O3? What is FePO4's compound name? What is the name of the ionic compound CAO? What is the name for the compound with the formula MgCl_2? What is the name of the covalent compound Cl2O?
It has been found in this work that a single covalent bond exists between the Sb and O and that vibration along the bond axis explains the IR and Raman active band at 685 cm−1. For the first time, we have shown that bismuth activated fluorapatite produces an analogous BiO ...

To confirm the presence of four covalent Kr–F bonds in KrF4, we perform an analysis of the Electron Localization Function (ELF) [56]. This dimensionless function, defined for every point in the crystal structure, spans values from 0 to 1. Values close to 1 are generally interpreted as in...

Al-FOH bond: 77.70 eV) relative to that of Al on C-PAFC (Al-F bond: 76.52 eV) explained higher fluoride uptake capacity of C-PACl. Less chloride was released from C-PACl than that from C-PAFC due to its hig...
but the process is difficult to achieve because the two reactions occur at close thermodynamic potentials and compete with each other. Rui Cao and coworkers report on the selective CO2RR in aqueous solutions utilizing covalent Co porphyrin polymers with fine...
