摘要
By employing functional ligand 3,6-bis（3,5-dimethyl-lH-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）/~, fl = 96.448（3）~, C23H23NsNi（NO3）2, M,. = 552.19, V = 1479.7（4） A3, Z = 2, Dc = 1.239 g/cm3,/ffMoKa） = 0.700 mm-1, F（000） = 572, the final R = 0.0566 and wR = 0.1336 for 1638 observed reflections with I 〉 2a（/）. 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.
