A novel Zn6Co3 cluster-based heterometallic coordination polymer, [Zn6Co3(PMG)(6)(H2O)(4)]center dot 12H(2)O (1), has been hydrothermally synthesized, in which the PMG(3-) (N-(phosphonomethyl)glycinate) as a multifunctional ligand was firstly formed via in situ decarboxylation from original ligand N-(phosphonomethyl)imino-diacetic acid during the hydrothermal reaction. The complex was characterized by elemental analysis, FT-IR, powder X-ray diffraction, thermal analysis and single-crystal X-ray diffraction techniques. Its structure features a 2D framework constructed by [Zn6Co3(PMG)(6)(H2O)(4)] pinwheel-like heteronuclear clusters, which contains rings with two tropisms. Through extensive O-H center dot center dot center dot O hydrogen bondings, the adjacent 2D layered structure further extends into a 3D supramolecular network. Moreover, the solid-state fluorescence property of this complex has also been investigated at room temperature, which exhibits a good fluorescent emission.
