A new one-dimensional azido-bridged manganese compound has been prepared and structurally characterized by X-ray diffraction. The complex [Mn（N3）2（H2O）3·C6H12N4]n crystallizes in space group Pnma with a = 6.5252 （5）, b = 9.3226（7）, c = 22.2070（15） ,A°, V= 1350.89（17） ,A°^3, Z = 4, Mr = 333.24, Dc = 1.639 g/cm^3, μ = 1.005 mm^-1 and F（000） = 692. The final refinement gave R = 0.0328 and wR = 0.0777 for 1085 observed reflections with I 〉 2σ（I）. The structure contains [Mn（N3）2（H2O）3]n polymeric chains and uncoordinated hexamethylenetetramine （HMTA） molecules with Mn/HMTA molar ratio of 1：1. The Mn atoms are bridged by end-to-end azido ligands to construct one-dimensional zig-zag infinite chains. Each Mn atom is six-coordinated by three N atoms of three azido ligands and three water O atoms, resulting in an octahedral geometry. Extending hydrogenbonding interactions involving water O atoms, azido and HMTA N atoms link the chains and HMTA molecules into a three-dimensional network.

It consists of discrete [Mn(phen)2(H2O)2]2+ cation, two acetate anions and six lattice water molecules. The MnII ion coordinated by four nitrogen atoms from two chelating phen and two oxygen atoms from two cis-related water molecules is in a distorted octahedral coordination environment. Two OAc- anions and six water molecules exist outside the [Mn(phen)2(H2O)2]2+ cation as counter ions and solvate molecules, respectively. The cations and anions are interconnected by the solvate water molecules which are hydrogen bonded to both aqua ligands and acetate oxygen atoms, building up the crystals of this compound to be a supramolecule-like aggregate.

The present study deals with some chemical behavior,including Cd extractability,species transformation and adsorption-desorption characteristics,of Cd in the rhizosphere(R) of wheat seedlings grown on both yellow-brown earth(YBE) and red earth (RE).Results indicated an increase of pH about 0.5 unit in the R of the yellow-brown earth and a decrease about 0.4 unit in the R of red earth in comparison with their respective bulk soils(NR).More Cd adsorbed and less Cd desorbed,and hence less Cd extracted in the R of YBE than those in the NR were *** opposite cases were got for the R of *** experiment showed that in the R of YBE,more Cd was bound to Mn oxides and organic matter,less Cd was in exchangeable form,and little Cd was bound to amorphous and crystal iron ***,little difference of the Cd species between the R and NR of RE was found. Regression analysis indicated that pH was one of the dominant factors affecting the chemical behavior of Cd in rhizosphere.
