Isoizomeric

Isoizomeric is a term used in chemistry to describe molecules that are isomers but differ in their "orientation" or arrangement relative to a central point or plane, particularly in the context of ring structures or complex molecular architectures. It is not a standard or widely recognized term in general organic chemistry nomenclature, which typically relies on more specific descriptors like stereoisomers, enantiomers, diastereomers, or positional isomers.

When the term isoizomeric might be encountered, it likely refers to a specific classification within a particular research context or a niche area of chemistry. The core idea is that two molecules share the same connectivity of atoms (making them isomers) but have distinct spatial arrangements that are not adequately captured by standard terminology. This could involve subtle differences in ring puckering, the relative orientation of substituents on a ring, or the conformation of flexible chains attached to a central core. Without a precise definition provided by its user, the meaning of isoizomeric remains context-dependent. It suggests a similarity in the overall structural framework but a difference in how parts of the molecule are oriented in three-dimensional space.
