“…The general structural features of the molecules are consistent with those observed for related gallium alkoxides (average GaϪO equatorial , GaϪO axial and GaϪN distances are 1.923 Å , 2.113 Å and 2.348 Å , respectively). [5,13] It is worth noting that the crystal structure exhibits disorder indicating the presence of the (R*,R*)- (Figure 2). These diastereomers result from the association of monomeric moieties of the same or opposite configuration as the chiral center in the O,N-chelating ligand.…”

The crystal structure analysis of model organogallium amine‐alkoxides Me2Ga(OCH2CH2CH2NH2) (2) and [Me2Ga{μ‐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.
