Synthesis and structure of nickel(II) compound with tetradentate schiff-base ligand and diazido monohydrate

The complex [Ni(L)(N-3)(2)].H2O (L=N,N'-Bis(2-pyridylaldehyde) condensation 1,3-diaminopropane) was synthesized by the reaction of NiCl2.H2O with 2-py ridylaldehyde and 1,3-diaminopropane and sodium azide in the ethanol. A sin gle-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)Angstrom, V=3637(1)Angstrom (3), Z=8, M-r=413.10,D-c=1 .509 g/cm(3), mu = 1.096 mm(-1), F(000) = 1712, T = 293(2)K, R = 0.0411, wR = 0.1048 for 2888 reflections with I >2 sigma (I). The distances between N i and N atoms (N(1), N(2), N(3), N(4)) range from 2.050(2) to 2.140(2)Angst rom. The distances of Ni-N(5) and Ni-N(8) are 2.115(3) and 2.133(3)Angstrom , 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) an d 2.893(0.5+x, y, 0.5+z)Angstrom, respectively.
