摘要：

Two iso-structural two-dimensional (2D) porous coordination polymers, which formulated as [Fe(1,3-di (4-pyridyl)propane)(2)(NCX)(2)](2) (X = S [1], Se [2]) and featured 2-fold interpenetration, have been synthesised and characterized. Crystal structure, Hirshfeld surfaces analysis and magnetic properties of them were described. The basic-unit of 1 and 2 was the 2D rhombic grids [2 x (4, 4)] network, and the intermolecular interactions in the crystals were dominated by C-H center dot center dot center dot pi, H-H and C-H center dot center dot center dot S (Se) contacts. The stronger ligand field strength of SeCN- than that of SCN- resulted to different magnetic properties: compound 1 shows paramagnetic property while 2 display displays an incomplete SCO transition approximately 30% conversion of high-spin (HS) to low-spin iron(II) sites with transition temperature of 100 K.
