This compound has isolated V4O92- layers made up of edge-sharing VO5 square pyramids. The V4O92- layers of [H2N(CH2)4NH2]V4O9 ([H2N(CH2)4NH2] = piperidinium) differ from those of two other ternary vanadium oxides, CaV4O9 and A2V4O9 (A = Rb, Cs), in the way the VO5 square pyramids are shared, and the magnetic susceptibilities of the three oxides are widely different in their maximum susceptibility values and the temperatures where these values occur. To explain these observations, the electronic structures of the three oxides were analyzed based on molecular orbital calculations.}, number={4}, journal={CHEMISTRY OF MATERIALS}, author={Zhang, YP and Warren, CJ and Haushalter, RC and Clearfield, A and Seo, DK and Whangbo, MH}, year={1998}, month={Apr}, pages={1059–1064} }

Compound 1 has As 3 groups, while compound 2 has infinite As ribbons on both faces of each layer. Unlike compound 1, compound 2 has substitutional defects where indium partially occupies each of the three independent germanium sites in the ratio of 1:5 for In:Ge. This partial occupancy makes 2 an electron-precise compound. The Ge(In)–Ge(In) bond of 2 is longer than the Ge–Ge bond of 1, and this bond lengthening effect was confirmed by performing DFT-MO calculations on the model compounds H 3 Ge–GeH 3 and H 3 Ge–InH − 3 . Possible implications of electron imprecise formulas determined by X-ray crystal structure determinations are discussed. Compound 1: space group P 2 1 / c with a =18.394 (8) A, b =19.087 (7) A, c =25.360 (3) A, β =105.71 (2)°, V =8571 (4) A 3 , and D calcd =4.45g/cm 3 for Z =4.
