Its structure possesses bilayer architectures constructed from Mn ions linked infinite Mn（BTC） chains which were build up from BTC ligand as the "T-shape" module and Mn as the linear module.The hydrogen-bond and π-π stacking interactions between bilayers make them three-dimensional channel-like interpenetrated frameworks.展开更多

Structure analysis shows that the compound consists of organic cations(Methyltriethylammonium) and inorganic anion chains (Ag2I3)n-. The inorganic moiety consists of AgI4 tetrahedron, which shares the same edges with adjacent AgI4 tetrahedrons to form one-dimensional infinite double chains along a-axis. There exists weak interaction among Ag…Ag atoms in the crystal. Anion chains are surrounded by Methyltriethylammonium cations. Anion chains and cations are in combination with each other by static attracting forces in the crystal to form so-called organic-inorganic hybrid structure. According to the crystal structure data, quantum chemistry calculation with DFT on B3LYP level was used to reveal the electronic structure of title compound. CCDC: 254288.展开更多
Two novel coordination polymers, [Cu(nip)(phen)]n (1) and [Co2(nip)2(phen)2]n (2), have been synthesized by hydrothermal synthesis using 5-nitroisophthalic acid (H2nip), 1,10-phenanthroline (phen) and metal salts and ...Two novel coordination polymers, [Cu(nip)(phen)]n (1) and [Co2(nip)2(phen)2]n (2), have been synthesized by hydrothermal synthesis using 5-nitroisophthalic acid (H2nip), 1,10-phenanthroline (phen) and metal salts and structurally characterized by X-ray single-crystal structure analysis. The results indicated that the nip ligand in compound 1 has a μ3 mono-atomic bridging-monodentate coordination mode and the structure is a two-dimensional network, while the nip ligand in compound 2 has a chelating-bridging coordination mode and the structure is a one-dimensional network.
