On the crystal engineering of organogallium alkoxides derived from primary-amine alcohols - Relationships between hydrogen bonding and donor-acceptor bonds

The crystal structure analysis of model organogallium aminealkoxides Me2Ga(OCH2CH2CH2NH2) (2) and (Me2Ga(mu -OCH2CH(CH3)NH2))(2) (3), demonstrate how hydrogen bonding can effectively compete with metal-ligand coordination preferences in determining the molecular and crystal structure and how conformational changes in a ligand and increased steric bulk on the carbon atom adjacent to the amine group can impart on a network morphology and molecular aggregations.
