The self-assembly of a prominent mixed-donor ligand, 5-[4-（1H-tetrazolyl）phen]isophthalic acid（H3TZPl）, with a Cd2＋ center generates two new metal-organic frameworks： [Cd（H2TZPI）2（H2O）2]n（JUC-163） and [Cd2...The self-assembly of a prominent mixed-donor ligand, 5-[4-（1H-tetrazolyl）phen]isophthalic acid（H3TZPl）, with a Cd2＋ center generates two new metal-organic frameworks： [Cd（H2TZPI）2（H2O）2]n（JUC-163） and [Cd2（TZPI）（μ3-OH）（H2O）2]-H2O.DMF（JUC-164）. The two complexes demonstrate different structures for the ligand＇s different coordination modes and configurations. JUC-163 shows a 2D layer structure and further forms into a 3D supramolecular framework by noncovalent interactions（C--H…O, O--H…N and π…π interactions）, whereas JUC-164 exhibits a fascinating 3D framework for the outstanding coordination modes and configurations of the ligand, which are fit for the complex structure. And also, the factor of different cadmium salts（chloride and nitrate） which are used in synthesis progress is worth to notice for the construction of the two distinct structures. The luminescent properties of these metal-organic frameworks were also investigated.展开更多
Crystal structure of the title compound C 16 H 25 O 2NS 2 has been determined by X-ray diffraction method. Its crystallographic data were as follows: M r=327.51, triclinic, space group P1, a=8.864(3), b=10.127(4), c=1...Crystal structure of the title compound C 16 H 25 O 2NS 2 has been determined by X-ray diffraction method. Its crystallographic data were as follows: M r=327.51, triclinic, space group P1, a=8.864(3), b=10.127(4), c=10.390(3) , α=105.94(3), β=103.10(2), γ=90.96(3)°, V=870.3(7) 3, Z=2, D c=1.250g.cm -3 , μ(MoKα)=2.966cm -1 , F(000)=176, a total of 3275 reflections measured (2θ max =50°), 2246[I5σ(I)] used in the refinement, R=0.067, R w=0.082. The result shows that the distances of N(1)-C(2) and N(1)-C(3) are longer than that of N(1)-C(11), which indicates that the interaction of C Ar -N sp 2 is stronger than that of C sp 3 -N sp 2 . Oxygen, nitrogen and sulfur atoms of the ring in the same plane was deduced from the least\|squares planes and the dihedral angles.展开更多

The structures of the compounds were confirmed by elemental analysis, IR, H-1 NMR and P-31 NMR. The results showed that the mixed-donor ligand (PNP) was coordinated to manganese only through the phosphorus atom.展开更多
