To provide a coordinate polymer metal complex compound single crystal having increased gas adsorptivity and a method for producing the compound.
The coordinate polymer metal complex compound single crystal is a porous bulk single crystal of a coordinate polymer metal complex compound having a composition having as a skeleton a coordinate polymer metal complex having a three-dimensional structure expressed by [M2(C6H2N2O4)2(C4H4N2)]4H2O as one unit, wherein M is a pentadentate metal element selected from Cu, Ni and Cd, in which complex the two-dimensional structures composed of the metal element M and 2,3-pyrazine dicarboxylate are bonded together through a column composed of pyrazine interposing a gap between the structures, and the gap is divided with the column to form pores. Water is supplied on an aqueous solution A of the pentadentate metal element salt and pyrazine to form a water layer, an aqueous solution B of 2,3-pyrazine dicarboxylic acid is supplied on the water layer at a supplying rate of 0.04-0.4 cm3/sec to form a layer of an aqueous solution B and the product is left to stand at room temperature.
