摘要：

The reactions of the highly flexible ligand 1,4-bis(imidazol-1-ylmethyl) benzene (bix) with manganese(II) azide and dicyanamide (dca), respectively, have afforded two 2-D coordination polymers, [Mn(N-3)(2)( bix)(2)](n) (1) {[Mn(dca)(2)(bix)(2)] . CH3OH}(n) ( 2), which have been characterized crystallographically. In both complexes, the metal ion is octahedrally coordinated by two axial azido or dca(-) ions, which compensate the charge, and four equatorial bix ligands in the trans conformation, and the bix ligands serve as the spacers between metal ions, resulting in 2-D ( 4,4) square grid layers. Based on the known examples of metal - bix complexes, a brief analysis of the flexibility of the bix ligand and some comments on the assembly are also presented.
