A Notable Difference in Photoluminescent Efficiency between a Newly Synthesized Asymmetric Dinuclear Cu(I) Cyano Complex Building Unit [Cu-2(CN)(5)](3-) and a Symmetric Unit [Cu-2(CN)(6)](4-)
A new cyano-bridged Cu(I)/Cd(II) coordination polymer K[CdCu2(CN)(5)]center dot dce center dot 3H(2)O (dce = 1,2-dicyanoethane) containing a novel asymmetric dinuclear Cu(I) building unit [Cu-2(CN)(5)](3-) was synthesized, and its emission intensity was very weak in contrast to very strong emission of CdCu(CN)(3)center dot hpn center dot 2H(2)O (hpn = 3-hydroxypropionitrile) containing an already known symmetric building unit [Cu-2(CN)(6)](4-).
