To obtain a carbon material compsn. capable of easily dispersing metal ions or a zero-valent metal in a molecular level by thermal decomposing a specified complex compd. obtd. from a [m+n] calixarene deriv. and a metallic compd.

A calixarene-metallic complex compd. represented by formula I or II is synthesized using [m+n] calixarene deriv. and a metallic compd. as starting materials and this complex compd. is carbonized by thermal decomposition at about 200-1, 500°C to obtain the objective metal dispersing carbon material compsn. In the formulae I, II, each of R1-R3 is H, 1-20C alkyl, 6-20C arom. hydrocarbon, etc., (m+n) is an integer of 4-10, L is an anion, a cation or a ligand, (x) is 1-10, M is a metal and (k) is the total number of the electric charges of metal ions. The compsn. has a porous structure derived from the crystal structure of the complex compd. and is fit for an electrode material of a cell, a DDS material, etc.
