摘要: A new two-dimensional polymeric manganese compound [Mn(PhCOO)(2)(4,4'-bipyridine)](n) I 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) angstrom, V = 2074.42(7) angstrom(3), Z = 4, M-r = 453.34, D-c = 1.452 g/cm(3), mu = 0.670 mm(-1) and F(000) = 932. The final refinement gave R = 0.0458 and wR = 0.1439 for 1358 observed reflections with 1 > 2 sigma(I). The complex consists of repeating units of Mn(PhCOO)2(4,4'-bipyridine). Each Mn center is six-coordinated 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 mu(1,3)-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.
