By employing functional ligand 3,6-bis(3,5-dimethyl-1H-pyrazol-4-yl)-9-methyl- 9H-carbazole, a novel luminescent Ni complex has been obtained. Its structure was characterized by single-crystal X-ray diffraction analysis. Crystal data: monoclinic, space group P2/c, a=13.4224(18), b=13.759(2), c=8.0633(17) , β=96.448(3)o, C23H23N5Ni(NO3)2 , Mr=552.19, V=1479.7(4)3 , Z=2, Dc=1.239 g/cm 3 , μ(MoKα)=0.700 mm -1 , F(000)=572, the final R=0.0566 and wR=0.1336 for 1638 observed reflections with I > 2σ(I). X-ray analysis indicates that each metal center coordinates with two N and two H atoms in tetrahedral interaction geometry. Weak interaction between Ni and N atom of pyrazole ligand and agostic bond (Ni···H-N interaction) play important roles in the formation of the 2-dimension framework. Significantly, this framework could pack into a tubular channel with NO3 - anions trapped inside.
In addition to the novel functionalized ligand 3,6-bis (3,5-dimethyl-1H-pyrazol-4-yl) -9-methyl-9H- carbazole, a novel luminescent Ni complex has been obtained. A = 13.4224 (18), b = 13.759 (2), c = 8.0633 (17), β = 96.448 (3) o, C23H23N5Ni (NO3) 2, Mr = 552.19, V = 1479.7 (4) 3, Z = 2, Dc = 1.239 g / cm 3, μ (MoKα) = 0.700 mm -1, F = 0.1336 for 1638 observed reflections with I> 2σ (I). X-ray analysis indicates that each metal center coordinates with two N and two H atoms in tetrahedral interaction geometry. Weak interaction between Ni and N atom of pyrazole ligand and agostic bond ( Ni ··· HN interaction) play important roles in the formation of the 2-dimension framework. Significantly, this framework could pack into a tubular channel with NO3 - anions trapped inside.
