Synthesis and Crystal Structure of a Supramolecular Complex [Mn（4 - PTZ）2 （H2O）4 ]·2H2O

The reaction of 5-(4-pyridyl) tetrazolate with MnCl2 led to a supramolecular compoundMn(4 PTZ) 2(H2O) 4].2H2O.The crystal structure of title compound was characterized by X-ray diffraction technique.The crystal structurebe longs totriclinic system with space groupP-1,and a = 0.73208(14) nm,b = 0.78961(15) nm,c =0.88483(17) nm,α = 90.411(3),β = 90.418(3),γ = 99.705(3),and Z = 1.The analysis of the crystal structure indicates that the title compound consists of one Mn atom,two 4-PTZ and four water molecules.The Mn atom has an octahedron coordination geometry and was six-coordinated with four oxygen atoms from four water molecules and two N atoms from two 4-PTZ ligands.The compound molecules were linked by different hydrogen bonds to form a 2D network,and then extended to a 3D structure by hydrogen bonds and π-π stack interactions.
