WebApr 4, 2024 · The solid-state structure of the AgRe4 cluster shows an unexpected asymmetric coordination motif, wherein the silver(I) cation has inserted into the Re-Re bond of one Re2(CO)10 moiety, while the other dirhenium carbonyl coordinates only over one metal atom towards the silver(I) cation. Occasionally, a moiety may contain smaller moieties and functional groups. A moiety that acts as a branch extending from the backbone of a hydrocarbon molecule is called a substituent or side chain, which typically can be removed from the molecule and substituted with others. Active moiety [ edit] See more In organic chemistry, a moiety is a part of a molecule that is given a name because it is identified as a part of other molecules as well.
