- 中文摘要: The crystal and molecular structure of the fore-coordinate complex Ni(C22H22N4) containing the tetramethyldibenzotetraaza[14] annulene ligand has been determined from three-dimensional X-ray diffraction data. The complex crystallized in the monoclinic space group C…-P2 1/n with cell dimensions a=14.7967(10), b=11.2169(6), c=11.4510(6) A, and β=98.467(5)° with z=4. The final agreement indices from the least-square refinement of 245 variables with 3111 observations F>3σ(F), are R=0.050, Rω=0.037. The structure has a pronounced saddle-shaped conformation with Ni atom at the saddle point coordinated to four nitrogen atoms. The average Ni-N distance is 1.866(3) A. The delocalized propane-1, 3-diiminato chelate rings and the benzene rings are linked by nominally single C-N bonds.
