Hydrothermal synthesis, structure and photoluminescent property of a novel sodium-pyrazinyltetrazole framework compound

abstract Article history:Received 8 April 2011Accepted 31 May 2011Available online 13 June 2011Keywords:Pyrazine tetrazolate (pzta)In situHydrothermalFramework A novel coordination polymer of sodium [Na 2 (Pzta) 2 (H 2 O) 2 ] n (1) has been synthesized hydrothermally byreacting pyrazine carbonitrile and sodium azide in the presence of aluminum(III) chloride as Lewis acidcatalyst. Complex 1 was characterized by elemental analysis, thermal gravimetric analysis and IRspectroscopy. Single crystal X-ray diffraction revealed that complex 1 has both distorted trigonal bipyramidaland square pyramidal coordination geometries around sodium atoms. Complex 1 represents the firsthydrothermally synthesized 1D sodium monotetrazole coordination polymer. Strong hydrogen bonds areformed between water molecules and nitrogen atoms of both pyrazine and tetrazole rings which result in theformationofa2Dmetallosupramolecular network.Theluminescence propertiesof1werealsoinvestigatedatroom temperature in the solid state.© 2011 Elsevier B.V.
