由1,3,5-三(1-咪唑基-亚甲基)-2,4,6-三甲基苯(titb)的乙醇溶液与四氟硼酸四乙腈合银水溶液扩散制备得到了一个含二配位银的M3L2型笼状化合物[Ag3(titb)2](BE4)3。该化合物属单斜晶系，空间群为C2/c,a=2.1794(3)nm,b=2.0201(4)nm,c=1.4813(2)nm,β=128.600(10)°,V=5.0967(14)nm^3,Z=4,Dc=1.701g/cm^3,F(000)=2592,R=0.0379,wR2=0.0964,一个BF4^-阴离子象一只“鸟”位于笼中，而另外两个处于笼子外面。

A novel M3L2 type cage-like compound, [Ag3(titb)2](BF4)3, was synthesized by diffusion method between the 1,3,5-tris (imidazol-1- ylmethyl)-2,4,6-trimethylbenzene (titb) in ethanol and aqueous solution of [AgCH3CN)4]BF4. The compound crystallizes in the monoclinic space group C2/c with a=2.1794(3)nm, b=2.0201(4)nm, c=1. 4813(2)nm, β=128.600(10)°, V=5.0967(14)nm^3, Z=4,Dc=1.701g/cm^3, F (000)=2592, R=0.0379, wR2=0.0964. One of the BF4^- anion locates inside of the cage like a 'bird' while the others are outside of the cage.
