【Abstract】 Ag3[(C5H4N)NH2]4(NO3)3,Mr=886. 09,orthogonal,space group Pccn,a=0. 799 0(2)nm,b=1. 6750(3) nm,c=2. 102 0(3) nm,V=2. 813 3 nm3,Z=4, Dc=2. 092 gcm-3, λ(Moka) = 0. 071 073 nm,μ=21. 156 cm,F(000) = 1736,final R=0. 043 and S=1. 400 for 1956 observed reflections. The ligand aminopyridine bridges two Ag atoms. One Ag atom coordinates with four N atoms of amino-group,forming distortional tetrahedral. Another one bonds to two N atoms of pyridine-group and three O atoms of nitrate anion, forming a pentacoordinated compound.更多还原
