of a range of metal complexes of Mn(II), Co(II), Ni(II) and Zn(II) with the ‘extended reach’ ligands O[iPr2SiO(CH2)npy]2 (n=0, 1 or 3, I–III) and with Cu(II), Cd(II) and Ag(I) for II; six of them have been shown by X-ray studies to have polymeric structures. The compounds M[O(iPr2SiOpy)2]2Cl2 (M=Co, Cu) form chains of 24-membered macrocycles, as does Co[O(iPr2SiOCH2py)2]2I2(H2O)2. A similar structure
据报道,制备了一系列具有“延伸”配体O [ i Pr 2 SiO(CH 2)n py]的Mn(II),Co(II),Ni(II)和Zn(II)金属配合物。2(ñ = 0,1或3,我- III)中,用铜(II),镉(II)和Ag(I)为II ; X射线研究表明其中六个具有聚合结构。化合物M [O(i Pr 2 SiOpy)2 ] 2 Cl 2(M = Co,Cu)与Co [O(i Pr 2 SiOCH 2 py)形成24元大环链。2 ] 2 I 2(H 2 O)2。Mn [O(i Pr 2 SiOCH 2 py)2 ] 2 Cl 2形成类似的结构,但在这种情况下,环为28元。复杂的Cu [O(i Pr 2 SiOpy)2 ] Cl 2形成52元大环的片,在节点处具有氯桥连的Cu 2 Cl 4单元。Cu 2 [O(i Pr 2 SiOpy)2 ] 4 Cl的结构图3包括由48元环构成的薄片,它
