摘要
Two mixed metal-organic coordination polymers, namely ([Zn(4-PTZ)(2)Cl-2]center dot 4H(2)O}(n). (1) and {[Cd-3(4-PTZ)(2) (H2O)(2)Cl-6]center dot 3H(2)O}(n) (2), were synthesized under hydrothermal condition using 5-(4-pyridyl)tetrazolate (4-PTZ), which exhibited diverse coordination modes in two complexes. The two compounds are both crystallized in a monoclinic system. Compound 1: a=0.691 75(8) nm; 6=2.668 8(3) nm; c=1.122 66(12) nm; beta=93.535 0(10)degrees; V=2.068 7(4) nm(3); Z=4; R-1=0.031 8 for I>2 sigma(I); wR(2)=0.082 9; space group P2(1)/n. Compound 2: a=1.897 13(13) nm; b=1.055 79(7) nm; c=1.446 49(10) nm; beta=102.489 0(10)degrees; V=2.828 7(3) nm(3); Z=4; R-1=0.026 2 for I>2 sigma-(1); wR(2)=0.134 3; space group C2/c. They are characterized by elemental analysis, IR spectroscopy and TGA. In addition, 1 and 2 have ultraviolet fluorescence emissions in the solid state at room temperature.
