چکیده انگلیسی
Two nickel (imidazole) complexes, Ni(im)6Cl2·4H2O (1) and Ni(im)6(NO3)2 (2) (im=imidazole) have been synthesized and characterized by elemental analysis, IR, UV, TG and single crystal X-ray diffraction. 1 crystallizes in the triclinic space group P-1 with a=8.800(6) Ã
, b=9.081(6)Â Ã
, c=10.565(7)Â Ã
, α=75.058(9)°, β=83.143(8)°, γ=61.722(8)°, V=718.3(8) Ã
3, Z=1 and R1 (wR2)=0.0469 (0.1497). 2 crystallizes in the trigonal space group R-3 with a=12.370(6)Â Ã
, b=12.370(6)Â Ã
, c=14.782(14)Â Ã
, α=90.00°, β=90.00°, γ=120.00°, V=1959(2) Ã
3, Z=3 and R1 (wR2)=0.0358 (0.0955). 1 and 2 exhibit different supramolecular network due to their different counter anions and different hydrogen bonding connection. In compound 1, [Ni(im)6]2+ cation and counter anions Clâ alternatively array in an ABAB fashion via N-Hâ¯Cl hydrogen bonding. In compound 2, the plane of each NO32â is almost parallel and each NO32â connect three different [Ni(im)6]2+ cations via N-Hâ¯O hydrogen bonding.
