摘要：
The complex [Ni（L）（N3）2](H2O (L=N,N（-Bis（2-pyridylaldehyde） condensation 1,3-diaminopropane） was synthesized by the reaction of NiCl2(6H2O 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 H2O（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.
