Auszug
Die Kristall- und die Molekületruktur von Zn(N2H4)2(H2Nʹ-NH · COO)2 wurde bestimmt. Die Kristalle bestehen aus einzelnen Molekülen, die durch Wasserstoffbindungen miteinander verknüpft sind. Jedes Molekül ist ein oktaedrisches Chelat. Die sechs Ecken des Koordinations-Oktaeders sind besetzt von zwei Stickstoffatomen des Hydrazin-Moleküle sowie von je zwei Stickstoff- und Sauerstoffatomen der Hydrazincarboxyl-Gruppe. Die Abstände der Zinkatome von den sie umgebenden Atomen sind: Zn-O = 2,05 Å, Zn-Ν = 2,25 Å und 2,17 Å. Die Abstände der Stickstoffatome sind 1,46 A im Hydrazin- Molekül und 1,39 A in der Hydrazincarboxyl-Gruppe. Die Atome N, C und beide O der Gruppe -NH · COO- liegen in einer Ebene mit den C-O-Abständen 1,30 Å und 1,25 Å, entsprechend den Abständen in der Carbonsäure und deren Verbindungen.
Abstract
The crystal and molecular structure of bis(hydrazine) zinc bis(hydrazincarboxylate- Nʹ,O), Zn(N2H4)2(H2Nʹ-NH · COO)2 , has been determined. The crystal structure consists of single molecules bound to one another by hydrogen bonds. Each molecule is an octahedral chelate. The six corners of the coordina・ tion octahedron are occupied by two nitrogen atoms belonging to two hydrazine molecules and by two nitrogen atoms and two oxygen atoms, all belonging to two hydrazincarboxylic groups. The bond distances between zinc and surrounding atoms are: Zn-O = 2.05 Å, Zn-Ν = 2.25 Å and 2.17 Å. The distances between nitrogen atoms, in hydrazinic groups, are: Ν-Ν = 1.46 Å, for the hydrazine molecule, and 1.39 Å, for the hydrazinic group of the acid. In the group -NH · COO- the atoms C, Ν and both O lie in the same plane. The distances C-O = 1.30 Å and 1.25 Å correspond to those found in carboxylic acids and carboxylates.
