报道一种新的四羧基桥联桨轮状二铜配合物的合成与晶体结构表征 .该配合物属于 P1空间群 ,其晶胞参数为 a=12 .65 2 (3 ) ,b=18.983 (4) ,c=9.10 2 (3 ) ,α=97.2 6(2 )°,β=10 7.3 8(2 )°,γ=10 2 .2 2 (2 )°.研究结果表明 ,在该配合物中轴向配位位置被硝酸根离子占据 .而轴向硝酸根离子上对 Cu2 +的配位显著增加了 Cu… Cu间的距离 (2 .73 8 ) This paper reports the synthesis and crystal structure characterization of a new tetracarboxylated bridged paddle-like copper complex, belonging to the P1 space group with unit cell parameters of a = 12 .65 2 (3), b = 18.983 ( Α = 97.2 6 (2) °, β = 10 7.38 (2) °, γ = 10 2 .2 2 (2) °. The results show that in the complex The axial coordination sites are occupied by nitrate ions, while the coordination of Cu2 + on axial nitrate ions significantly increases the distance between Cu and Cu (2.73 8)
