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

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 pre ferences in determining the molecular and crystal structure and how conform ational changes in a ligand and increased steric bulk on the carbon atom ad jacent to the amine group can impart on a network morphology and molecular aggregations.
