Abstract: | Solvothermal reactions of terphenyl-2,5,2′,5′-tetracarboxylic acid (H4qptc) and MII (M = Mn, Fe) in the presence of 1,2-bis(diphenylphosphino)ethane (dppe) afford two new coordination polymers, M(qptc)(dppe-O)] n (M?=?Mn (1), Fe (2)) (1,2-bis(diphenylphosphoryl)ethane?=?dppe-O). The structures have been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses, IR, TGA, and magnetism. The MII in 1 and 2 are linked by qptc4? to form 2-D layers, which are further connected via the oxidized dppe (dppe-O) exhibiting a (4,6)-connected network with the (54.62)(510.63.7.8) topology. |
