Abstract
A manganese coordination polymer [(phen)MnCl2]n (phen = 1,10-phenanthroline,C12H8N2) with formula C12H8Cl2MnN2 and Mr = 306.04 has been synthesized and structurally characterized by single-crystal X-ray diffraction. The crystal is of monoclinic, space group C2/c with a = 17.2451(10), b = 10.4431(8), c = 7.0349(5) (A),β= 111.983(1)°, V= 1174.82(14) (A)3, Z = 4,Dc= 1.730 g/cm3,μ = 1.552 mm-1, F(000) = 612, T= 293(2) K, R = 0.0343 and wR = 0.0877 for 826 observed reflections with I ＞ 2σ(Ⅰ). The title compound possesses a one-dimensional chain structure composed of polymeric (phen)MnCl2 units in which the manganese (Ⅱ) ion is chelated by one phen and bridged by double chloro-ligands with the Mn-N distance of 2.257(3) (A) and Mn-Clof 2.4775(8) and 2.6568(7) (A). The Mn…Mn separation is 3.853 (A).
