Discrete homo Cu–Cu–Cu and hetero Cu–Pd–Cu or Cu–Co–Cu metal arrays are prepared within an organic-pillared coordination box by inserting M(II)-azaporphine/porphine cartridges (M = Cu(II), Pd(II) or Co(II)), where the metal arrays show unique spin interactions in ESR: in particular, Δms = 3 for the Cu–Cu–Cu array.
The present invention provides a novel method for identifying a molecular structure by single crystal X-ray analysis. A single crystal that gives an X-ray diffraction spectrum sufficient for determining the structure of the molecule can be efficiently obtained by including a test molecule in a metal complex and then crystallizing the test-molecule-including metal complex. By analyzing this single crystal by X-ray analysis, it is possible to determine the structure of the test molecule without obtaining a single crystal of the test molecule. With the method according to the present invention, the structure of a test molecule in a trace amount of sample can also be determined.
