Two U0^(2+)_(2) complexes{[C_(5)H_(4)N(0)C=N-N=C(PhHPh)C=N-N=C(0)-C_(5)H_(4)N]2U02(CH30H)}(I)and{[C_(5)H_(4)N(0)ON-N=C(Ph)-(Ph)C=N-N=C(0)-C_(5)H_(4)N]2U02(C_(5)H_(4)N(0)C=N-NH_(2))}(II)were synthesized and characterized by IR,elemental analysis and thermal stability analysis,and the crystal structures were determined by X-ray diffraction.The crystal of complex I belongs to monoclinic system,space group P2_(1/n) with α=11.7678(4),6=16.9667(6),c=14.3051(5)A,β=98.918(3)°,Z=4,F=2821.64(17)A^(3),D_(c)=1.837 Mg·m^(-3),μ(MoKα)=5.805 mm^(-1),F(000)=1504,R=0.0346 and wR=0.0688.The crystal of complex II is of triclinic system,space group Pi with a=11.6417(5),b=11.7297(5),c=14.2197(5)A,α=71.697(4)°,β=86.020(3)°,γ=71.572(4)°,Z=2,K=1748.02(12)A^(3),D_(c)=1.742 Mg·m^(-3),μ(MoKa)=4.704 mm^(-1),F(000)=894,R=0.0283 and wR=0.0537.The U1 is a seven-coordinate pentagonal bipyramidal configuration in I and an eight-coordinate hexagonal dipyramidal configuration in II.The thermal stability and quantum chemical calculations of I and II were also investigated.
