Dans ce travail, 54 nouveaux composés de coordination homogènes et à ligands mixtes de nitrates de magnésium et de calcium ont été synthétisés ; leur individualité et la coordination des ligands et des anions nitrates à l’ion central ont été déterminées par analyse de la phase des rayons X et spectroscopie IR. La structure cristalline du composé de coordination [Ca(NO3)2(NC5H4CONH2)2(H2O)2] a été déterminée pour la première fois par analyse de diffraction des rayons X ; les produits de la thermolyse ont été identifiés et les propriétés thermiques des composés synthétisés ont été déterminées. Les paramètres énergétiques, la distribution des charges sur les atomes, la géométrie et la réactivité des composés synthétisés ont été déterminés par des méthodes de chimie quantique. Sur la base de l’analyse de l’activité biologique, un nouveau stimulant pour les plantes agricoles, Ca(NO3)2-CO(NH2)2-CS(NH2)2, a été identifié dans un certain nombre de composés synthétisés. L’application de la préparation a permis d’accélérer la durée de germination, de raccourcir la période de végétation et d’augmenter le rendement du coton.
