| Abstract: 3-(salicyloylhydrazono)butan-2-one oxime H2L (1，C11H13N3O3) and two nickel complexes with 3-(salicyloylhydrazono)butan-2-one oxime, [Ni(HL)(C5H5N)2(CH3COO-)](2) and [Ni(HL)2]·2DMF（3）, have been prepared and characterized. The crystallographic data are space group P21/n, a=0.451 87(2) nm, b=2.086 8(1) nm, c=1.224 48(9) nm, β=94.974(3)°, V=1.150 3(1) nm3, Z=4, Dc=1.358 g·cm-3, F(000)=496, μ=0.101 mm-1, R=0.0435, and wR=0.142 5 for compound 1; space group P21/n, a=1.362 39(8) nm, b=1.345 37(6) nm, c=1.438 54(7) nm, β=113.138(3)°, V=2.424 6(2) nm3, Z =4, Dc=1.398 g·cm-3, F(000)=1 064, μ=0.843mm-1, R=0.042 4, and wR=0.116 6 for compound 2; space group P21/c, a=1.104 22(7) nm, b=2.860 1(1) nm, c=1.114 13(7) nm, β=114.589(5)°, V=3.199 5(3) nm3, Z=4, Dc=1.398 g·cm-3, μ=0.667 mm-1, F(000)=1 416, R=0.057 6, and wR=0.1535 for compound 3. The neighboring molecules of compound 1 are connected together with intermolecular hydrogen bonds, forming a two-dimensional supramolecular architecture. The Ni atom in compound 2 has a distorted octahedral coordination. Three donors (carbonyl oxygen, hydrazide nitrogen and oxime nitrogen) of the ligand HL- and one acetate oxygen comprise the basal plane. Two nitrogen atoms of two pyridine molecules occupy axial positions. There are two intramolecular hydrogen bonds of O-H(oxime)…O(acetate) and O-H(phenol)…N(hydrazide) in the molecule of compound 2. The Ni atom in compound 3 is octahedrally coordinated by four N atoms and two O atoms from two ligands HL-. There are intramolecular hydrogen bonds of O-H…O and O-H…N and intermolecular hydrogen bond of O-H…O in compound 3. CCDC: 221532, 1; 221533, 2; 221534, 3. |
