【摘要】 合成了一种由银直接连接Anderson型钼氧酸盐阴离子形成的新型二维配合物,并用单晶X射线衍射仪测定了其晶体结构,用元素分析仪及红外光谱等进一步表征了化合物的结构。含银配合物为三斜晶系,P-1空间群,晶胞参数为a=1.1676(3)nm,b=1.2205(4)nm,c=1.2566(6)nm;α=95.313(5)°,β=113.974(5)°,γ=117.079(3)°;V=1.3695(9)nm3,Z=1。配合物中,相邻的4个{Fe(OH)6Mo6O18}3-之间存在两种连接方式,一种是被孤立的{AgO6}八面体通过端氧沿b轴连接起来;另一种则是被2个共边相连的{AgO6}八面体通过端氧沿b轴桥连起来。这两种连接方式沿c轴方向交替排列形成了二维网状结构。更多还原

【Abstract】 A new two-dimension coordination polymer by connecting silver directly with Anderson type molybdate anion,( NH4) 3{ Ag[Fe( OH) 6Mo6O18]} { Ag2( H2O) 2[Fe( OH) 6Mo6O18]} ·11H2O has been synthesized in aqueous.The structure is determined by single crystal X-ray diffraction and characterized by elemental analysis,IR spectroscopy and thermogravimetric analysis.The polymer is triclinic,space group P-1,its crystal data is a = 1.167 6( 3) nm,b = 1.220 5 ( 4) nm,c = 1.256 6 ( 6) nm,α = 95.313 ( 5) °,β = 113.974 ( 5) °,γ = 117.079( 3) °,V = 1.369 5( 9) nm3,Z = 1.There are two different link modes.One is four adjacent Anderson anions linked through one { AgO6} octahedron via terminal oxygen atoms along the b-axis,and the other one is four adjacent Anderson anions linked through two { AgO6} octahedron via terminal oxygen atoms along the b-axis.The two different modes are arranged alternately along the c-axis to form a 2D network.更多还原
