A one dimensional coordination polymer, [(C7H18N)(Ag2l3)]n((C7H18N)^ =Methyltriethylammonium) has been successfully synthesized and characterized by X-ray single-crystal diffraction method. Structure analysis shows that the compound consists of organic cations(Methyltriethylammonium) and inorganic anion chains (Ag2l3)s^-.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 Methyhriethylammonium 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.

In the title complex, there exist two kinds of metal centers in the structure, cadmium ions and sodium ions. The Cd（Ⅱ） atom shows a distorted pentagonal-dipyramidal geometry defined by two O and one N atoms from one deprotonated pyda ligand and four N atoms from four μ-1,1,3 azido groups. The adjacent cadmium atoms are bridged via two μ-1,1,3 azido groups, along the c axis to afford an extended chain. There is also a 2D network which is comprised of binuclear subunits [NaE（H2O）6] connected by O atoms from coordinated water between the adjacent Cdn（pyda）n（Na）2n infinite chains. Furthermore, each cadmium atom is connected with four adjacent sodium atoms through the bridging N3- ligand in μ-1,3 patterns. Thus, the title complex exhibits a novel three-dimensional network structure.
