Metallic radius van der Waals radius edit Theionic radius,rion, is a measure of the size of anionin acrystal lattice. It is measured in either picometres (pm) or Angstrom (Å), with 1 Å = 100 pm. Typical values range from 30 pm (0.3 Å) to over 200 pm (2 Å). ...

It has been quantitatively studied how the A cation size and the ionicity of the B-O bond could influence the covalency of the Ir-O bond. By means of EXAFS analysis, the ionic radius of octahedrally coordinated Ir-VI could be determined to be 0.521 Angstrom from the average Ir-O bond ...
The possible reason may be that anions are further away from the 1,2,4-triazolium cation in the order of I− > Br− > Cl− as a result of their radius [68]. For the same Br−, the TOF value was in the order of SBA-15-IL2Br > SBA-15-IL1Br > SBA-15-IL3Br. In ...
