An energetic cuprous azide complex, [Cu2(2apyz)(N3)2] n (1) (2apyz = 2-aminopyrazine), has been synthesized through hydrothermal method by utilizing the reducibility of H3PO3 and structurally characterized by single-crystal X-ray diffraction. Complex 1 has a 2-D layer structure constructed from copper(I) bridged by azide and pyrazine. Catalysis research shows 1 can promote the burning rate of the main component of rocket propellant.

Utilizing Co(2-mpac)2(H2O)2 as molecular building block, a coordination polymer, [Co2(2-mpac)4(4,4'-bpy) · 2H2O]n (1) (2-mpac = 5-methyl-2-pyrazinecarboxylic acid; 4,4'-bpy = 4,4'-bipyridine), was synthesized and structurally characterized by X-ray single crystal diffraction. Elemental analysis, infrared, and magnetism are presented. Variable temperature magnetic susceptibility measurements exhibit weak antiferromagnetic interaction between Co centers in 1.

A coordination polymer, [Co(2-mpac)2(4,4′-bpy)·(4,4′-bpy)] n (2-mpac: 5-methyl-2-pyrazinecarboxylic acid; 4,4′-bpy: 4,4′-bipyridine), has been synthesized through hydrothermal synthesis and structurally characterized by X-ray single crystal diffraction. Single crystal X-ray diffraction analysis reveals a 3-D network featuring a 1-D tunnel filled with 4,4′-bpy molecules. Elemental analysis, IR, thermogravimetric analysis, and magnetic properties are presented. [ABSTRACT FROM PUBLISHER]
