Abstract: The first 2D open-architecture Ba(II) perchlorate with organic template, [(H+4-MP)2Ba(ClO4)4] n (1) (4-MP=4-methylpyridine), has been synthesized and characterized by single-crystal and powder X-ray diffraction, elemental analysis, IR, 1H NMR, TGA, DSC and fluorescence properties. The Ba(II) centers of the icosahedral (BaO12) were chelated through μ 2-perchlorate donors to form a 2D (4,4) topology with the protonated amine molecules mounted to the main body of the inorganic framework by N–H⋯O H-bonding interactions. To verify the generality of the synthetic methods, 4-MP has been replaced by other different amine templates. The results have shown that the crystallization processes are very sensitive to the induced effect of the organic templates. [Copyright &y& Elsevier]
