摘　　要：The crystal structure of the title complex having the stoichiometric formula [Ni\|(phen) 3]Pic 2·2CH 3CN (Pic=picrate anion; phen=1,10\|phenanthroline) has been determined by single-crystal X-ray diffraction. The crystal (C 52 H 34 N 14 O 14 Ni, M r=1137.63) belongs to the triclinic system, space group P1(#2) with the following crystallographic parameters: a = 14\^130(1), b=15\^256(3), c=13.673(2); α=109.11(1), β =90.92(4), γ=66.75(3)°; V=2537\^72 3, D c=1.489g/cm 3, μ(MoKα)=4.66cm -1 , F(000)=1168, Z=2, and final R=0.062 and R w=0.078 for 4917 observed reflections (I>2.00σ(I)). The analytical results of crystal structure and spectroscopic properties show that nickel(II) cation coordination environment is a distorted octahedral geometry, the Ni 2+ ion is coordinated with six nitrogen atoms~ of three phen directly, while two picrate anions and two acetonitrile molecules do not take part in coordination~.
