ResumoDie Kristallstrukturen von γ-CoV2O6 (I) und MnV2O6 (II) wurden mit Röntgen-Einkristalltechnik untersucht. I kristallisiert im NiV2O6-Typ, Raumgruppe C21P1 mit a = 7,164 Å; b=8,872 Å; c=4,806 Å; α=90,29°; b=93,66°; γ=102,05°; Z=3. II gehört dem Brannerittyp an, Raumgruppe C2h3-C2/m mit a=9,289 Å; b=3,535 Å; c=6,763 Å; b=112,64°; Z=2. Die Kristallstrukturen und ihre Beziehungen zueinander werden diskutiert. The crystal structures of γ-CoV2O6 (I) and MnV2O6 (II) were examined by means of single-crystal X-ray crystallography. I crystallizes with the NiV2O6 structure, space group C21-P1; a=7.164 Å; b=8.872 Å; c=4.806 Å; α=90.29°; β=93.66°; γ=102.05°; Z=3. II is of the Brannerite type, space group C2h3-C2/m; a = 9.289 Å; b = 3.535 Å; c = 6.763 Å; β=112.64°; Z=2. The crystal structures and their relationships to each other are discussed.
