摘要
A new two-dimensional polymeric manganese compound [Mn（PhCOO）2（4,4＇-bipyridine）]n 1 has been prepared and structurally characterized by X-ray diffraction. The complex crystallizes in space group Pbcn with a = 18.7158（2）, b = 11.6919（3）, c = 9.4799（2）A, V = 2074.42（7）A^3, Z = 4, Mr = 453.34, Dc = 1.452 g/cm^3, μ = 0.670 mm^-1 and F（000） = 932. The final refinement gave R = 0.0458 and wR = 0.1439 for 1358 observed reflections with Ⅰ〉 2σ（Ⅰ）. The complex consists of repeating units of Mn（PhCOO）2（4,4＇-bipyridine）. Each Mn center is sixcoordinated by four carboxylate O atoms of four benzoate anions and two pyridyl N atoms from bipy ligands to furnish a slightly distorted octahedral geometry. The two adjacent Mn atoms are connected by a pair of μ1,3-carboxylate groups to form infinite chains, which are further interlinked by bipy to complete a 2D grid network. The magnetic property of the polymeric complex has also been investigated.
