Synthesis and crystal structure of a new tridentate Ni(II) complex {Ni(H2O)3[Ph2(o-Ph-N-C7H7N)]PO}Cl2

A new tridentate Ni(II) complex {Ni(H2O)(3)[Ph-2(o-Ph-N-C7H7N)]PO}Cl-2 was synthesized by the reaction of a new ligand Ph-2 (o-Ph-N-C7H7N)]PO with NiCl2 in CH3CH2OH. The complex was characterized by X-ray single crystal diffraction. The crystal structure of the complex belongs to monoclinic space group P2(1)/n, a=1.259 28(9) nm, b=1.201 24(8) nm, c=2.039 03(14) nm, V=3.016 8(4) nm(-3), Z=4, and R-1=0.047 1, wR(2)=0.120 5. And a molecular CH2Cl2 is filled in the crystal structure.
