Synthesis, Crystal Structure, and Adsorption Properties of Werner-type Cu(II) Complex [Cu(CF3SO3)2(4-methylpyridine)4]

A Werner-type Cu(II) complex, alpha-[Cu(CF3SO3)(2)(4-mepy)(4)] (alpha-PAC-1-CF3SO3, PAC: porous assembly of coordination complex and 4-mepy: 4-methylpyridine), was synthesized, crystallographically characterized, and its adsorption properties were compared with those of the derivative alpha-[Cu(PF6)(2)(4-mepy)(4)] (alpha-PAC-1-PF6).
