The assembly of metal ions Zn2+, Co2+ and H2E2Ge2O3 ligand under mild hydro- thermal conditions leads to a mixed 3D transition zinc-cobalt-organogermanate framework, Zn0.88Co0.12(E2Ge2O3) (1, E =-CH2CH2COO-). The structure was determined by single-crystal X-ray diffraction and further characterized by IR spectroscopy, elemental analysis, energy-dispersive X-ray analysis, inductively coupled plasma, powder X-ray diffraction, thermogra- vimetric analysis and fluorescence spectroscopy. Compound 1 crystallizes in the chiral space group P212121, with a = 4.9096(5), b = 8.9031(11), c = 24.046(3) , V = 1051.0(2)3, C6H8Ge2O7Zn0.88Co0.12, Mr = 401.88, Z = 4, Dc = 2.540 g·cm-1, μ = 7.875 mm-1, F(000) = 775, GOF = 1.016, the final R = 0.0324 and wR = 0.0642. The structure of 1 is built up by Ge-O sheets with Ge6 rings and Zn/Co-carboxyl layers. It should be mentioned that although the whole E2Ge2O32-ligand exhibits only one kind of coordination mode, it plays two roles in forming the structure: SBU and linker. In this situation, the E group of H2E2Ge2O3 ligand becomes a determining factor for structural dimensionality. In addition, it displays blue-violet emission light and shows high thermostability.
