Preparation and Characterization of Organic-inorganic Perovskite-like Formate Mn(HCOO)3[(CH3)2NH2]

Metal-organic frameworks Mn(HCOO)3[(CH3)2NH2] (DMMnF) materials are prepared by hydrothermal growth technique. We analyze its crystal structure by X-ray Diffraction (XRD), chemical composition by infrared spectroscopy(IR).The results show that DMMnF belong to trigonal system, space group is R3-CH, the lattice constant is a=8.3330 (17) A, c= 22.947 (11) A, γ=120°,V=1379.09 (10) A3, Z=6.The morphology of DMMnF crystal is rhombohedral, and the large flat surface is (012). IR spectra shows that organic functional groups of DMMnF are dimethylamino and formate.
