| Abstract: | A novel manganese coordination polymer Mn(C5H2N2O6)·2H2O]4 has been synthesized and it was characterized by elemental analysis,FTIR and X-ray diffraction single-crystal structure analyses.Crystal data:monoclinic,space group P2(1)/c,a=6.4824(13) A,b=6.1325(12) A,c=19.980(4) A,α=90 deg,β=91.925(2) deg,γ=90 deg,V=793.8(3) A3,M =245.05,Z=4,Dc = 2.050Mg.m-3,F(000)=492,Absorption coefficient:μ= 1.671mm-1,Final R indices:R1=0.0263,wR2=0.0692.Single crystal structure determination reveals that the title complex is a novel one-dimensional coordination polymer.The local coordination environment around manganese ion is a distorted octahedron.Two 2D layer super molecular complex systems are formed by the hydrogen bonds and weak interactions between neighboring single cells.Further,some nanometer empties are found in direction in pack structure. |
