Abstract: A new nickel (II) complex with bis-schiff bases from picolinaldehyde N-oxide and 1,2-propanediamine, [Ni (piopn) (H_2O)_2] (ClO_4)_2 has been synthesised and its crystal structure has been determined. The crystal belongs to monoclinic system, space group C_c, with cell dimensions: a=0.7397(3) nm, b=1.3187(7) nm, c=2.5502(14) nm, β=102.18(4)°, V=224.10 nm, D_c=1.71 g·cm~(-3), F(000)=1135.8, μ=11.65 cm~(-1). According to the semiempirical MO theory calculation, the relationships between IR frequency shifts of ν_(C=N) and ν_(N-O) bands and their characteristics of chemical bonds have been discussed.
