报道两个新型单核镉配合物[Cd(NTB)(η1-NO3)(SCN)(H2O)3(1)和[Cd(NTB)(η2-OAc)(N3)]·CH3OH·H2O(2),其中配体NTB为三(2-苯并咪唑甲基)胺.配合物中镉离子均为七配位变形五角双锥配位构型,其中四个氮原子来自配体NTB,另外三个配位位置由小分子辅助配体填充.两个配合物中存在着多种形式的氢键.此外,对化合物1和2的光谱性质做了进一步的研究和讨论.
Two new mononuclear cadmium( Ⅱ ) complexes, [Cd(NTB)(η1-NO3)(SCN) (H2O)-] (Ⅱ) and [Cd (NTB) (η2-OAc) (Na)-] · CH2OH · H2O (2) (NTB =tris (2-benzimidazolymethyl)amine) have been synthesized and their structures have been determined by X-ray crystallography. The coordination polyhedron for central cadmium atom in both complexes can be regarded as a distorted heptacoordinate pentagonal bipyramid, including four N atoms from ligand NTB and three coordination sites accomplished by other additional small ligands. Many types of hydrogen bonds exit in these two complexes and sustain their structures. Moreover, the spectral properties of 1 and 2 have been further studied and discussed.
