为了研究过渡金属借助氢键引导的自组装,合成了线性刚性配体对二苯甲酸与钴(II)、4-氨基吡啶和水的配合物Na2(4-apyH)2[CoCl2(H2O)4·(tp)2](tpH2=p-phthalicacid,4-apy=4-aminopyridine).并采用X射线衍射法对配合物进行了晶体结构的测定.结果是结构简式C26H30CoN4O12Na2Cl2,相对分子质量Mr=766 35,三斜晶系,空间群为P1,晶胞参数a=7 875(2) A(1 A=10-10m),b=9 818(2) A,c=10 892(2) A,α=77.26(3)°,β=77 31(3)°,γ=84 22(3)°,V=800 1(3) A3,Z=1,Dc=1 590g·cm-3,μ=0 798mm-1,F(000)=393.结果表明:晶体分子中含三维氢键网状结构,每单元中心都以CoCl2O4六配位方式形成八面体构型.
In order to study the self-assembly of transition metal with hydrogen bonding, a series of linear rigid ligands, Na2 (4-apyH) 2 [CoCl2 (H2O) 4 (Tp) 2] (tpH2 = p-phthalicacid, 4-apy = 4-aminopyridine) .The crystal structure of the complex was determined by X-ray diffraction.The results are simple C26H30CoN4O12Na2Cl2, relative molecular mass Mr = 766 35. Triclinic system with space group P1, unit cell parameters a = 7 875 (2) A (1 A = 10-10 m), b = 9 818 (2) A, c = 10 892 (2) A , α = 77.26 (3) °, β = 77 31 (3) °, γ = 84 22 (3) °, V = 800 1 A3, Z = 1, Dc = 1 590 g · cm -3 = 0 798mm-1, F (000) = 393. The results show that the crystal contains three-dimensional hydrogen bond network structure, and each unit center forms an octahedron structure by the six-coordination of CoCl2O4.
