Abstract: The compound of [(NH3)5Co(C4H4N2)Ag(H2O)2(C4H4N2)Co(NH3)5](NO3)7· 4H2Ois sinthesized, and 1098. Thecompound is crystalized in monoclinic,space group C2/c,with a=9. 431 (2)Å, 6=12. 374(2)Å, c=33. 716(6)Å,β=92. 42(1)Å,V=3922. 6Å, Z=4, μ(MoKa,λ=0. 7.1070A)-18. 4 cm-1, F(000)=2248, T=298K, R=0. 038, Rw=0. 038 for 2272 significant reflections. The silver shows square plane coordination, two water molecules in axial positions, each pyrazine bridge the silver and one cobalt. The cobalts are six coordinated by nitrogens, one from pyrazine and others from NH3groups, forming an octahedral coordination.
