properties of two dinuclear copper(II) coordination compounds containing the ligand N3-salicyloylpyridine-2-carboxamidrazonato (abbreviated as spa) are reported. Compound 1, bis[(N3-salicyloylpyridine-2-carboxamidrazonato-N1,N2O)aquacopper(II)nitrate], [Cu(spa)(H2O)(No3)]2, Cu2C26H26N10O12, crystallizes in the triclinic space group P 1 , with , a = 8.898(1), b = 12.472(4), c = 14.063(5) A , α = 91.15(3)
摘要报道了两种含有配体N3-水杨基吡啶吡啶-2-羧酰胺基氮杂(简称spa)的双核铜(II)配位化合物的晶体结构,光谱和磁性。化合物1,双[(N3-水杨基吡啶吡啶-2-羧酰胺基氮杂-N1,N2O)aquacopper(II)硝酸盐],[Cu(spa)(H2O)(No3)] 2,Cu2C26H26N10O12在三斜空间群P 1中结晶。其中,a = 8.898(1),b = 12.472(4),c = 14.063(5)A,α= 91.15(3),β= 97.48(2),γ= 102.25(2)°,V = 1511.8 A 3,Z = 2(核单位)。基于3147个反射的最小二乘优化,I>2σ(I),收敛到R = 0.0501和Rw = 0.0581。此结构中存在两个晶体学独立的五配位铜(II)原子,它们的键合距离和键角略有不同。两种金属离子均处于正方形锥体环境中,其基础平面由两个氮,spa配体的
