摘要：The organic salt, (H2Bpy)(cda)2, was synthesized by the reaction of sodium carbamyldicyanomethanide, 4,4′-bipyridyl and manganese(Ⅱ) perchlorate in water solution. The crystal belongs to monoclinic, space group C2/c with α=20.333(7), b=6.177(2), c=15.566(5)A,β=116.860(5)°, V=1744(1)A^3, Z=4, C18H14N8O2 (Mr=374.37), Dc=1.426g/cm^3, F(000)=776,μ=0.100mm^-1 and λ=0.71073A. The structure was refined to R=0.0560 and ωR=0.1072 for 590 observed reflections (I>2σ(I)). Two nitrogen atoms of the 4,4′-bipyridyl molecule bonded to two hydrogen ions, resulting this neutral molecule into a divalent cation. Through the interaction of colorless H2bpy cation and colorless cda anion the red neutral organic salt was formed.
