摘要

Dichloro[1,2-bis (diphenylphosphino) ethane]nickel2+ (NiC12(dppe)) is an organic compound containing C26H24P2(dppe) molecules and Cl-,Ni2+ ions.The large-size NiCl2(dppe) single crystals with longest dimension of 4 mm were grown by the method of slow evaporation of organic solution.Single crystal x-ray diffraction spectrum indi-cates that the single crystal is of high quality.Magnetization results of the NiC12(dppe) single crystals show an anisotropic paramagnetism behavior and diamagnetic background,which come from Ni2+ ions and benzene ring,respectively.How-ever,according to the specific heat results with temperature down to 0.1 K and magnetic field up to 14 T,no expected field-induced quantum phase transition was observed in NiC12(dppe) single crystals.
