Synthesis and crystal structure of trinuclear potassium(I) complex with oxy-bridged bis(gem-dinitro)furazan and triaminoguanidinium

L L. An, Q. Q. Yu


A furazan-based trinuclear potassium(I) complex derived from the oxy-bridged bis(gem-dinitro)furazan (OBNF) and triaminoguanidinium (TGA) units was synthesized and characterized by elemental analyses, nuclear magnetic resonance (NMR) and infrared (IR) spectroscopy. The single crystal X-ray structure of the complex has been determined. It revealed that the asymmetric unit contains two crystallographically independent OBNF2 anion, one triaminoguanidinium cation, three potassium cations (K+) and one crystallized water molecule. In the crystal structure, intra- and intermolecular hydrogen bonding interactions as well as weak π−π stacking interactions were observed, which are beneficial to form the net-like structure.
