Abstract: [Mn(L-Phe) 2·H 2O)] n (Phe=phenylalanine) with a single stranded coordination polymer has been synthesized by self-assembly of manganese salt and phenylalanine and characterized by X-ray single-crystal diffraction method. The complex crystallizes in the orthorhombic, space group P2 12 12 1 with a = 6.0911(1), b = 10.3642(1), c = 30.4321(7) Å, V = 1921.16(6) Å 3, Z = 4, D c = 1.387 g/cm 3, C 18H 22N 2O 5Mn, M r = 401.32, F(000) = 836 and μ(MoKα) = 0.717 mm -1. The final R = 0.0614 and wR = 0.1412 for 2291 observed reflections with I > 2σ(I). The magnetic behavior study shows that there exist super-exchange antiferromagnetic interactions between the magnetic centers through the effective exchange pathway of the carboxylate group.
