The invention separating material and separation method make it possible to separate and collect 1,3-butadiene selectively from a mixed gas containing 1,3-butadiene and a C4 hydrocarbon other than 1,3-butadiene. A separating material capable of adsorbing 1,3-butadiene selectively includes: a dicarboxylic acid compound (I) represented by formula (I) (wherein R1, R2, R3 and R4 independently represent a hydrogen atom, an alkyl group or the like); a metal ion such as a zinc ion and a cobalt ion; and a metal complex having such a structure that multiple pseudo-diamondoid frameworks are intruded mutually, wherein each of the pseudo-diamondoid frameworks comprises an organic ligand (II) that is represented by formula (II) (wherein X represents —CH2—, —CH2—CH2—, —CH═CH— or the like; and R5, R6, R7, R8, R9, R10, R11 and R12 independently represent a hydrogen atom, an alkyl group or the like) and is capable of being bidentately coordinated with the metal ion. |
