Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 14389-12-9, is researched, Molecular C6H5N5, about Solid state coordination chemistry of polyoxomolybdate clusters: Hydrothermal synthesis and structures of [{Cu3II(4-pt)2(4-Hpt)2(H2O)2}{Mo8O26}]·2H2O and [{Cu10I(4-pt)6(4-Hpt)2}{Mo8O26}]·2H2O (Hpt = 5(4′-pyridyl)tetrazole), the main research direction is copper pyridyltetrazole polyoxomolybdate preparation magnetic susceptibility thermolysis; crystal structure copper pyridyltetrazole polyoxomolybdate.Synthetic Route of C6H5N5.
The hydrothermal reactions of MoO3, Cu(CH3CO2)2·H2O and 5(4′-pyridyl)tetrazole (4-Hpt) yielded a low temperature Cu(II) phase [{Cu3(4-pt)2(4-Hpt)2(H2O)2}{Mo8O26}]·2H2O (1·2H2O) and a high temperature Cu(I) material [{Cu10(4-pt)6(4-Hpt)2}{Mo8O26}]·2H2O (2·2H2O). The two-dimensional structure of 1 is constructed from β-octamolybdate clusters embedded in a {Cu3(4-pt)2(4-Hpt)2(H2O)2}n4n+ network. The copper(II)-pyridyltetrazolate layer consists of trinuclear clusters of corner-sharing copper ‘4 + 2’ octahedra linked through the dipodal 4-pt ligands. In contrast, the three-dimensional structure of 2 contains the {β-Mo8O26}4- building block embedded in a three-dimensional {Cu10(4-pt)6(4-Hpt)2}n4n+ framework. The copper(I)-pyridyltetrazolate substructure consists of chains of Cu tetrahedra and trigonal planes bridged by tetrazolate groups and connected through exo-catenate {CuN2O} trigonal planar units bonding to the pyridyl nitrogens of the dipodal ligand.
