摘　　要：水热法合成了一个无机-有机杂化的NH_(4)[Cu_(3)^(I)(C_(10)H_(8)N_(2))_(3)Mo_(8)O_(26)]化合物,通过元素分析和单晶X-射线衍射进行了表征。化合物为三斜晶系,P1空间群,晶胞参数a=1.08763(9)nm,b=1.12674(10)nm,c=1.13067(10)nm,α=68.4820(10)°,β=83.523(2)°,γ=64.4180(10)°,V=1.16095(2)nm^(3),Z=1,Dc=2.661 g/cm^(3),Mr=1860.73,μ(MoKα)=35.22 cm^(-1),F(000)=888,R=0.0478,wR=0.099。化合物的结构包含2个结晶学上独立的铜原子、不连续的多氧阴离子β-[Mo_(8)O_(2)6]4-和无限扩展的[Cu I(C_(10)H_(8)N_(2))]链。每一个铜原子为类似的{CuN_(2)}配位模式,被4,4’-联吡啶连接成一维沿a轴方向的[Cu(C 10 H 8 N 2)]+链。分子结构中存在氢键和π…π作用。对化合物的热稳定性、荧光性质也进行了研究。A hybrid compound,NH_(4)[Cu^(I)_(3)(C_(10)H_(8)N_(2))_(3)Mo_(8)O_(26)](1),has been hydrothermally synthesized and structurally characterized by elemental analysis and single crystal X-ray analysis.The compound crystallizes in triclinic,space group P1 with a=1.08763(9)nm,b=1.12674(10)nm,c=1.13067(10)nm,α=68.4820(10)°,β=83.523(2)°,γ=64.4180(10)°,V=1.16095(2)nm^(3),Z=1,Dc=2.661 g/cm^(3),Mr=1860.73,μ(MoKα)=35.22 cm^(-1),F(000)=888,R=0.0478,wR=0.099.The structure is composed of discrete polyoxoanionβ-[Mo_(8)O_(2)6]4-and infinite[Cu I(C_(10)H_(8)N_(2))]chains with two crystallographically independent copper atoms.Each of two copper atoms exhibits similar{CuN_(2)}coordination mode,and is linked by 4,4’-bipyridine molecule to one-dimensional[Cu(C_(10)H_(8)N_(2))]+chain along the a axis.There exists hydrogen bonds andπ…πinteractions in the molecular structure.Moreover,the thermal stability and photoluminescence property are studied as well.
