Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
Six inorganic−organic compounds based on [MoxOy]n- chains, [Ag2(quinoxaline)2Mo4O13] (1), [Cu2(DMPz)2Mo4O13] (2) (DMPz = 2,5-dimethylpyrazine), [Cu2(4-PBIM)2Mo4O13] (3) [4-PBIM = 2-(4-pyridyl)benzimidazole], [Cu(OPBIM)(H2O) Mo3O10]·H2O (4) [OPBIM = 2-(2-ol-3-pyridinio)benzimidazole], [Co(3-HPBIM)2 (H2O)2Mo6O20] (5) [3-HPBIM = 2-(3-pyridyl)benzimidazolium], [Ni(3-HPBIM)2(H2O)2Mo6O20] (6), have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction. Compounds 1 and 2 represent the first two examples of three-dimensional frameworks constructed from [Mo8O26]n4n- anion chains integrated by M−L polymeric cation chains. Compounds 3 and 4 reveal the peripheral decorated [Mo8O26]n4n- and [Mo3O10]n2n- one-dimensional chains, respectively. The isostructural compounds 5 and 6 feature two-dimensional networks formed from [Mo3O10]2n4n- infinite chains linked by [Co(3-HPBIM)2]4+ fragments. The molybdate chains in compounds 1−3 and 4−6 represent three isomeric forms of [Mo8O26]n4n- and two [Mo3O10]n2n- chains, respectively.
