Water structure: A rare 3D water-chlorin architecture

In this work, we report a new Co(II) compound, namely Co(L)2(Cl)2 ·7H2O(1) featuring a 1D tape structure, was obtained by hydrothermal self-assembly of CoCl2 and 2,4,5-tri(4-pyridyl)-imidazole (L). The structure feature of it is the 3D water-chlorin architecture based on two kinds of chain-like water structures classified by the C4 and T4(0)A2 pattern, respectively.
