Sažetak
Polydentate Schiff base ligands and their metal complexes have been used extensively because of their preparative availability and structural variability. This kind of compounds having the system of delocalized Pi-electron density play important role as building blocks of new materials for non-linear optical material applications. Crystallographic data: C_28H_18N_2O_2Ni, M_r =236.6, Monoclinic, P 2_1/n, a = 15.867(3) A, b = 7.577(1) A, c = 16.407(2) A, beta = 97.98^o, V = 1953.2(3) A^3, Z = 4, D_calc = 1.61 g cm^-3, F(000) = 976, mu(MoK_alpha) = 1.025 mm^-1, lambda(MoK_alpha) = 0.71073 A, R = 0.037, wR = 0.047. The nickel atom coordination environment is, as expected, square planar with fairly regular dimensions. Bond lengths Ni-N and Ni-O, respectively vary from 1.828(1) to 1.851(1) A, and the metal atom displacement from the least-square NNOO plane is 0.008 A only. Almost planar butterfly-like molecules dimerise through the Pi- Pi stacking of an entirely delocalized Pi-electron system (Fig. 1). The non-H atom contacts other than Ni...Ni (3.291 A) ranging from 3.198(3) to 3.500(3) A are responsible for the dimerisation. The dimers, slightly shifted relatively to each other, stack along [010] direction with inter- dimer contacts being 3.264(3) to 3.477(3) A. The [010] columns of dimers link together through extremely weak attraction forces. The solid-state intermolecular interactions are probably either of the M-Pi (ligand) or Pi-Pi ligand nature.^1 ^1.
