摘要

PROBLEM TO BE SOLVED: To provide a new metal complex having gas-storing property, a gas- storing apparatus using the gas-storing property of the complex and an automobile furnished with the gas-storing apparatus. ;SOLUTION: This three-dimensional organic metal complex is composed of a bivalent metal ion, an organic ligand capable of forming a bidentate coordination and 2,3-pyrazinedicarboxylic acid and has a laminar structure. The complex can adsorb and store gas molecules in the space of crystal lattice. A compound having a relatively rigid molecular skeleton such as pyrazine and 4,4'- bipyridyl and having coordinating atoms on both ends is used as the organic ligand capable of forming a bidentate coordination. The gas-storing apparatus is composed of a pressure vessel having a gas-inlet and outlet port and a gas- storing three-dimensional organic metal complex composed of a bivalent metal ion, an organic ligand capable of forming a bidentate coordination and 2,3- pyrazinedicarboxylic acid, having a laminar structure and held in the space of the vessel. The automobile is furnished with the gas-storing apparatus.;COPYRIGHT: (C)1997,JPO
