The biological activities of the metal complexes of derivatives of benzaldehyde nitrogen mustard were investigated against 〓,〓 and SMMC-7721 cell lines. The interesting results were found. When the non-activity ligand combines with cobalt and nickel , the complexes have good antitumor activity, while active ligand binds to the metal, the complex has no activity, indicating there are synergic effect and counteraction between the metals and the ligands.

对所获得苯甲醛氮芥衍生物的金属配合物进行研究，观察它们对SMMC-7721、〓细胞株的作用，发现某些有趣的实验结果，无活性的配体，当与钴，镍形成配合物后，具有很好的抗肿瘤活性，而有活性的配体形成配合物后无活性，揭示在它们存在有协同作用及拮抗作用。

The Molar conductivity indicates that all the complexes are nonelectrolyte. IR spectra show the ligand is bonded with RE ion through its oxygen atom in hydroxyl group of phenol; NO3 is coordinated as a symmetrical chelating bidentate group; the coordinated atoms of DMF and DMSO are the oxygen atoms in carbonyl and sulfoxyl groups. Fluorescence spectrum suggests that the Tb3+complexes have characteristic luminescence and its fluorescence intensity is enhanced after doping with La3+, Gd3+, Y3+, influence of doping ions and neutral ligands have also been discussed.

摩尔电导率表明，所有配合物均为非电解质；红外光谱及核磁共振氢谱表明，对叔丁基杯[8]芳烃通过酚羟基的氧原子与稀土离子配位；硝酸根为双齿螯合配位；DMF和DMSO则分别通过羰基氧和亚砜基氧与稀土离子配位；配合物的荧光光谱表明，所有Tb的配合物具有较强的特征荧光，掺杂La~(3+)、Gd~(3+)、Y~(3+)离子对Tb~(3+)的荧光有较强的增强作用。

Cu and Co ions are coordintated with six oxygen atoms from two water molecules and four ligands to form an octahedral geometry. Each ligand links two metal ions in a μ2-bridge coordination mode and two-dimensional wavelike structures are formed.

Cu和Co均为六配位，八面体构型，每个金属离子与4个配体和2个水分子配位，每个配体采取μ2-桥联模式，形成二维层状结构。
