Coordination polymers are a class of materials
composed of metals or metal clusters (the ‘‘node’’)
coordinated to multi-functional organic ligands (the
‘‘linker’’) [1].During the last two decades, design and
synthesis of novel metal–organic coordination
polymers are attracting more attention, not only for
their interesting molecular topologiesbut also for their
potential applications as functional materials, ions
exchange, catalysis, molecular recognition, nonlinear
optics, molecular magnetic materials, electrical
conductivity, separation and gas storage [2]. Solidstate crystal-to-crystal transformations involving
coordination polymers induced by light, heat, guest
removal, uptake or exchange, expansion of
coordination numbers, oxidation of metal centers,
condensation, or reactions between the ligands are
very fascinating and one of the hot topics in solidstate chemistry [3]. Solid state reactions by manual or
mechanical grinding solid reactants together with
either no added solvent or only nominal amounts for
molecular synthesis have triggered lots of
attention.Mechanochemical synthesis, a burgeoning
field in coordination polymers, has been utilized to
synthesize various coordination polymers from the
reactants without solvents [4].
