    Description / Table of Contents: The Crystal and Molecular Structure of triptych-Boroxazolidine (Triethanolamine Borate)The crystal structure of triptych-boroxazolidine, C6H12BNO3, has been determined by X-ray diffraction. The intensity data were collected by a Pailred diffractometer and the structure was solved by direct methods. The molecule has threefold symmetry along the intermolecular B—N bond with the length 1.677 ± 0.006 Å.
    Notes: Die Struktur von triptych-Boroxazolidin, C6H12BNO3, wurde röntgenographisch mit Hilfe direkter Methoden bestimmt. Das Molekül besitzt eine dreizählige Symmetrieachse entlang einer innermolekularen B—N-Bindung mit der Länge 1.677 ± 0.006 Å.

    Description / Table of Contents: Tetrameric Dioxo(oxalato)vanadates(V). The Crystal Structure of K[VO2(C2O4)] · 2H2oThe red compounds M1 [VO2(C2O4)] · nH2O (M1 = Na, K, NH4, Rb, 1/2 Sr) contain, as has been shown by X-ray crystal structure analysis, the tetrameric, cyclic anion [{VO2(C2O4)}(H2O)2]4-. Each vanadium atom is octahedrally coordinated by one terminal and two bridging oxygen atoms, one water molecule, and a bidentate oxalate ligand. Pairs of VO6-octahedra are formed by sharing an edge. Two pairs are then joined together by sharing vertices.
    Notes: Die roten Dioxo(oxalato)vanadate(V), M1[VO2(C2O4)] nH2O (M1 = Na, K, NH4, Rb, 1/2Sr) enthalten, wie durch eine Röntgenstrukturanalyse an K[VO2(C2O4)] 2H2O ermittelt wird, das tetramere, cyclische Anion [{VO2(C2O4)}4(H2O)2]4-. Alle Vanadinatome sind oktaedrisch von einem endständigen und zwei verbrückenden Sauerstoffatomen, von einem Wassermolekül und einem Oxalat-Ion als zweizähnigem Ligand koordiniert. Je 2 Oktaeder sind über eine gemeinsame Kante zu einem Paar verknüpft; zwei Paare bilden dann über zwei einfache Sauerstoffbrücken (Spitzenverknüpfung) die tetramere Einheit.
