Abstract
Two new Co(II) coordination polymers, namely [Co(FA)(bix)] n (1) and [Co(FA) (bib) (H2O)2] n (2) (H2FA = fumaric acid, bix = 4,4′- bis(imidazol-1-ylmethyl)benzene, bib = 1,4-bis(imidazolyl) butane), have been successfully synthesized under hydrothermal conditions. Single-crystal X-ray analysis reveals that compound 1 is a two-dimensional (2D) layer framework, which is further packed into a 3D interdigitated framework, while compound 2 is a 3D framework and can be simplified into a fourfold interpenetrated dia topological net. Thermal analysis shows that compounds 1–2 possess different thermal stabilities.
