| Abstract: | The complex Ni(L)(N3)2](H_2O (L=N,N(-Bis(2-pyridylaldehyde) condensation 1,3-diaminopropane) was synthesized by the reaction of NiCl2(6H_2O with 2-pyridylaldehyde and 1,3-diaminopropane and sodium azide in the ethanol. A single-crystal X-ray study shows that the complex is a six-coordinated nickel (II) with an octahedral environment compound (C15H18N10NiO). The crystal is orthogonal, space group Pbca, with unit cell parameters: a = 13.577(3), b = 15.261(3), c = 17.554(4) ?, V= 3637(1) ?3, Z=8, Mr=413.10, Dc=1.509 g/cm3, ( = 1.096 mm－1, F(000) = 1712, T = 293(2)K, R = 0.0411, wR = 0.1048 for 2888 reflections with I >2( (I). The distances between Ni and N atoms (N(1), N(2), N(3), N(4)) range from 2.050(2) to 2.140(2)?. The distances of Ni-N(5) and Ni-N(8) are 2.115(3) and 2.133(3)?, respectively. The solvent molecule H_2O(O(1)) is linked by hydrogen bonds with O(1) and N(5) and N(8) atoms. Their distances are 2.881(+x, +y, +z) and 2.893(0.5+x, y, 0.5+z)?, respectively. |
