<P>PROBLEM TO BE SOLVED: To provide a metal complex which can store a large quantity of acetylene gas at a pressure low enough to avoid decomposition explosion. <P>SOLUTION: The acetylene storage material having the chemical formula: [M<SB POS="POST">2</SB>(pdc)<SB POS="POST">2</SB>(ap)]<SB POS="POST">n</SB>(wherein, M is a divalent transition metal cation; pdc is 2,3-pyridinedicarboxylic acid ion or 2,3-pyrazinedicarboxylic acid ion; ap is a pyridine derivative defined by formula (A); and n=1 to 3): is obtained by mixing a divalent transition metal cation, a first ligand obtained by neutralizing at least one of 2,3-pyridinedicarboxylic acid and 2,3-pyrazinedicarboxylic acid, and a second ligand which is a pyridine derivative having the following structural formula, at a mole ratio of 2:2:1 in water or a polar organic solvent completely compatible with water and thereby causing reaction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
