A porous coordinatively unsaturated metal complex comprises metal complex units. Each metal complex unit includes a first metal and an organic ligand. The metal complex units are connected one another through a second metal (a connecting metal). The porous coordinatively unsaturated metal complex has voids formed by the connection. Voids have a size of 10 Å or more. The first metal is rendered to a coordinatively unsaturated state in the metal complex unit. With this arrangement, not only low-molecular weight compounds but also general compounds can be introduced as substrates. Further, the porous coordinatively unsaturated metal complex has high catalytic activity or high molecule retainability.
