Chemistry is traditionally divided into organic and inorganic chemistry. name: Bis(benzonitrile)palladium chloride, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 14220-64-5
Synthesis, spectroscopic and crystallographic studies on two copper(II) benzimidazole complexes: Supramolecular frameworks built from N-H…O, N-H…Cl and O-H…Cl hydrogen bonds
The tridentate ligands 2,6-bis(benzimidazole-2?-yl)pyridine (L 1) and N,N-bis(benzimidazole-2?-yl-methyl)amine (L2) with N3 donor set form the corresponding mononuclear [Cu(L 1)(ClO4)(Cl)].H2O] (1) and [Cu(L 2)(Cl2)].H2O (2) complexes, which have been characterized by elemental analysis, UV-Vis spectra, IR, EPR and magnetic moment studies. Single crystal X-ray structure studies for both the complexes show that coordination geometries around the copper centre are best described as distorted square pyramidal with three nitrogen atoms of tridentate ligand and a chloride ion defining the equatorial planes. The apical positions in the complexes are occupied by a perchlorate O atom in 1 and a chloride ion in 2. Metal directed assembly of infinite two-dimensional supramolecular network stabilizes the crystal structures of both complexes in the solid state. The global magnetic interactions in complexes 1 and 2 are found to be paramagnetic with mueff values of 1.65 BM and 1.63 BM, respectively, which are typical for a Cu(II) d9 system.
