【Abstract】 Two compound crystals of (Hdafo)2·2H2O (1) and (Hdafo)2·2H2O (2) were obtained when we tried synthesizing the mixed ligand compounds of Zinc (Ⅱ)and Cobalt(Ⅱ)with 4,5 diazafluorene 9 one(dafo) and o phthalic acid, respectively. Their structure was determined by single crystal X ray diffraction. The crystals all belong to monoclinic system, C2/c space group with crystallographic data:(Hdafo)2·2H2O, a=1.6768(5)nm, b=1.2052(3)nm, c=1.3888(4)nm, β=116.793(3), V=2.5053(12)nm3, Z=4, F(000)=1232, Mr=609.57, Dc=1.616g·cm-3, μ(MoKα)=1.444mm-1, R1=0.0373, wR2=0.0765; (Hdafo)2·2H2O, a=1.6787(4)nm, b=1.2078(3)nm, c=1.3911(4)nm, β=116.665(3)°, V=2.5204(11)nm3, Z=4, F(000)=1220, Mr=603.13, Dc=1.589g·cm-3, μ(MoKα)=1.142mm-1, R1=0.0257, wR2=0.0654. The constitutes of the two compounds were proved by elemental, IR Spectra and thermal analyses. CCDC: 1, 198516; 2, 198517.更多还原
