Coordination polymers are promising photoluminescent materials
because of their high thermal stability, structure and metaldependent
emissions. The electronic properties of the transition
metal ions make them particularly attractive for the preparation
of luminescent complexes, which are characterized by a larger
variety of coordination spheres and emitting levels [12,52–54]. In
addition, it is known that most luminescence silver(I) compounds
show their luminescence properties at low temperature, whereas
only few of them are luminescent at room temperature [55,56].
