Abstract: The single crystal of Mn (15-Crown-5) (NCS)2 was obtained by solvent evaporation method, and the structure was solved from X-ray diffraction data by direct and Fourier methods.The crystal belongs to a triclinic system, space group is P1 with unit cell parameters: a=O.7126(2) nm, b=O.8469(1) nm, c=1.6031(4) nm, a=74.55(2)°β=76.29 (2)°, γ=74。 05(2)°, and Z=2, V=0.8825(4) nm3, Dx=1473 kg/m3, p=O.6956 lnm-1,F (000)=406- Mn (Ⅱ) coordinates derectly with five oxygen atoms of the 15-mcrown-5 and two nitrogen atoms of SCN- to form a seven coordinated compound.The five oxygen atoms lie in a plane approximatively- Mn(Ⅱ) is in the centre, and the two SCN- are situated on both sides of the plane.Mn(Ⅱ) adopts sp3d3 hybrid orbitals to form coordinated bonds.
