摘要: 用缓慢挥发法合成了一个六核Ni(Ⅱ)的配位聚合物[Ni6(H2O)6(HTMT)6]·3(C2H5)3N·7H2O(1)(H3TMT=三聚硫氰酸),并用红外、元素分析及单晶衍射进行表征。该配合物属于三方晶系,R3c空间群,晶胞参数为a=b=1.8697(3)nm,c=3.9825(8)nm,γ=120°。晶胞体积V=12.057(4)nm3,Dc=1.596gcm-3,Z=6,μ=1.91mm-1,F(000)=6095,R=0.047,wR=0.151。X单晶衍射表明,6个Ni(Ⅱ)与6个HTMT2-和6个水分子形成一个六核的构筑单元,这个六核构筑单元又通过氢键作用形成三维结构。同时在室温条件下测定了该配合物的荧光性能。 |

Abstract: The title complex, [Ni6(H2O)6(HTMT)6]·3(C2H5)3N·7H2O (1) (H3TMT=trithiocyanuric acid), was synthesized by slow evaperation, which was characterized by IR, elemental analysis, and single crystal X-ray diffraction. This complex crystallizes in trigonal, space group R3c, with a=b=1.8697(3) nm, c=3.9825(8) nm, γ=120°, V=12.057(4) nm3, C36H77N21Ni6O13S18, Mr=1941.36, Dc=1.596 gcm-3, Z=6, μ=1.91 mm-1, F(000)=6095, the final R=0.047, wR=0.151 for [Ni6(H2O)6(HTMT)6]·3(C2H5)3N·7H2O (1) observed reflections (I>2σ(I)). X-ray diffraction analysis reveals that the six nickel(Ⅱ) atoms are bridged by six HTMT2- and six water molecules into a hexanuclear building unit, the neutral hexanuclear building units are further connected into a three-dimensional framework through the O-H…O and O-H…N hydrogen bonding interactions. The photoluminescent property of complex (I) was also studied at room temperature. |
