In dieser Arbeit wurden 54 neue homogene und gemischtligandige Koordinationsverbindungen von Magnesium- und Calciumnitraten synthetisiert; ihre Individualität und die Koordination von Liganden und Nitratanionen an das Zentralion wurden durch Röntgenphasenanalyse und IR-Spektroskopie bestimmt. Die kristalline Struktur der Koordinationsverbindung [Ca(NO3)2(NC5H4CONH2)2(H2O)2] wurde zum ersten Mal durch Röntgenbeugungsanalyse bestimmt; Thermolyseprodukte wurden identifiziert und die thermischen Eigenschaften der synthetisierten Verbindungen wurden bestimmt. Energieparameter, Ladungsverteilung an den Atomen, Geometrie und Reaktivität der synthetisierten Verbindungen wurden mit quantenchemischen Methoden bestimmt. Auf der Grundlage der Analyse der biologischen Aktivität wurde ein neues Stimulans für landwirtschaftliche Pflanzen, Ca(NO3)2-CO(NH2)2-CS(NH2)2, in einer Reihe von synthetisierten Verbindungen identifiziert. Die Anwendung des Präparats führte zu einer Beschleunigung der Keimzeit, einer Verkürzung der Vegetationsperiode und einer Steigerung des Baumwollertrags.
