Isoelectronicity is a phenomenon observed when two or more molecules have the same structure (positions and connectivities among atoms) and the same electronic configurations, but differ by what specific elements are at certain locations in the structure. For example, CO, NO +, and N 2 are isoelectronic, while CH 3 COCH 3 and CH 3 N = NCH 3 are ...
Isolobal compounds are analogues to isoelectronic compounds that share the same number of valence electrons and structure. A graphic representation of isolobal structures, with the isolobal pairs connected through a double-headed arrow with half an orbital below, is found in Figure 1. Figure 1: Basic example of the isolobal analogy
As introduced by Gerhard Herzberg, [1] building off of work by R. S. Mulliken and Friedrich Hund, bond order is defined as the difference between the numbers of electron pairs in bonding and antibonding molecular orbitals. Bond order gives a rough indication of the stability of a bond. Isoelectronic species have the same bond order. [2]
Isostructural chemical compounds have similar chemical structures."Isomorphous" when used in the relation to crystal structures is not synonymous: in addition to the same atomic connectivity that characterises isostructural compounds, isomorphous substances crystallise in the same space group and have the same unit cell dimensions.

Borazine, also known as borazole, inorganic benzene, is an inorganic compound with the chemical formula B 3 H 6 N 3. In this cyclic compound, the three BH units and three NH units alternate. The compound is isoelectronic and isostructural with benzene. For this reason borazine is sometimes referred to as “inorganic benzene”.
A structural analog, also known as a chemical analog or simply an analog, is a compound having a structure similar to that of another compound, but differing from it in respect to a certain component. [1] [2] [3] It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or ...
Justin Baldoni disclosed a photo of handwritten notes allegedly from his meeting with an intimacy coordinator, a meeting he claims in his lawsuit Blake Lively chose to skip.
Boron nitride is a thermally and chemically resistant refractory compound of boron and nitrogen with the chemical formula BN.It exists in various crystalline forms that are isoelectronic to a similarly structured carbon lattice.
