[Mn(L-Phe)2@ H2O]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 P212121 with a = 6.0911(1), b = 10.3642(1), c = 30.4321(7) A, V= 1921.16(6) A3, Z= 4, Dc= 1.387 g/cm3, C18H22N2O5Mn, Mr = 401.32, F(000) = 836 and μ(MoKoα) = 0.717 mm-1. The final R = 0.0614 and wR = 0.1412 for 2291 observed reflections with L＞ 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.
