A three-center, two-electron bonding interaction in which a hydrogen atom is bonded to both a carbon atom and a metal atom, such as the interaction of a CH bond and an unsaturated transition-metal compound.

These conformational isomeric species have different receptibility towards agostic interaction.
Carbon-donor ligands are excluded for cyanides and fulminates; agostic bonding by C-H groups acting as two-electron donors is not covered, presumably because compounds with these kinds of interactions are treated as organometallics rather than coordination compounds.
