| Abstract: | A novel coordination polymer {Mn(m-cpdba)(H_2O)_4]·H_2O}_n 1 has been synthesized and characterized. Single-crystal X-ray diffraction analysis reveals that compound 1 contains one-dimensional single-stranded helical chains, in which the chirality of a stereo-chemically labile amine of the ligands can be locked by the Mn(Ⅱ) ion via coordination bonds and transferred to the whole coordination polymeric chain, exhibiting an identical absolute con-figuration. Crystal data for 1: C_(14)H_(17)Mn_1N_3O_(13), M_r = 490.25, space group C2/c, α= 18.5177(18), b = 6.6194(5), c = 31.563(4) A, β = 105.046(5)°, Z = 8, V= 3736.2(7) A~3, Dc= 1.743 g/cm~3, F(000) = 2008 andμ = 0.786 mm~(-1). |
