| Abstract: A Cu(Ⅰ) complex [Cu(INHPy)(PPh3)2] ·(ClO4)·0.75(C2H5OH) was obtained through self-assembly between [Cu(PPh3)2(MeCN)2]ClO4 and Schiff base 2-pyridylcarboxaldehyde isonicotinoyl hadrazone(INHPy), the structure of which was characterized by elemental analysis, IR spectrum and X-ray diffraction. Single crystal X-ray analysis indicates that this compound crystallizes in triclinic system, space group P1 with parameters: a=1.180 7(2) nm, b=1.330 0(3) nm, c=1.568 6(2) nm. α=100.91(1)°, β=108.863(2)°, γ=95.51(2)°. V=2.382 0(7) nm3, Z=4 , Dc=1.332 g·cm-3, F(000)=1 032, μ=0.634 mm-1. At the same time, we studied the title complex interacting with DNA with resonance light-scattering spectrum. The results showed that intensities of RLS signal are direct proportion to the concentration of DNA, (ΔI=0.804+23.770C, r=0.995). CCDC: 231388. |
