مستخلص: Two new hybrid compounds, [Cu(1)(phen)(H2O)][Cu(2)(phen)(H2O)]([Cu(3)]0.25(H2O)][P2Mo5O23]·3.75H2O (1) and [Cu(en)2]1.5[P2Mo5O23]2·(enH2)3·2H2O (2) (phen = 1,10-phenanthroline, en = ethylenediamine), have been hydrothermally synthesized and characterized by IR, UV–Vis spectroscopy, X-ray photoelectron spectroscopy (XPS), powder XRD analyses, TG analyses, cyclic voltammogram analyses, elemental analyses, and single crystal X-ray diffraction analyses. Single crystal X-ray diffraction analyses reveal that the two compounds have a 1-D chain structure formed by Strandberg-type POMs and TMCs with –A–B–C–B–A–B–C–B– linking mode, then further extend into a 2-D layer structure through π⋯π or hydrogen bond interactions.

We control the coordination modes of H3MIDC via hydrazine and obtained a series of coordination compounds containing honeycomb-like [M3(MIDC)2]nlayers. We also investigated the effects of different neutral terminal or bridging ligands on [M3(MIDC)2]nlayers. Coplanar [M3(MIDC)2]nlayers and 4,4-bipy were used to construct 3-D frameworks of1and2. Puckered [M3(MIDC)2]nlayers were found in3–5;4is the first [M3(L)2]nlayer structure with two crests and troughs during each period (L = imidazole-4,5-dicarboxylic acid or its analog). Compound5is the first puckered [M3(L)2]nlayer structure decorated by chelating neutral ligands. Compound1exhibits weak blue photoluminescence in the solid state at room temperature. Variable-temperature magnetic susceptibility measurements of2–5indicate strong antiferromagnetic interactions. Using a method, which can effectively control the coordination mode of H3MIDC, we constructed a series of new coordination compounds containing honeycomb-like [M3(MIDC)2]nlayers.
