1 Source of materials
An amount of 0.107 g 4-pyridinecarboxaldehyde (1.0 mmol), 0.153 g 2-hydroxyisonicotinohydrazide (1.0 mmol), 0.040 g NaOH (1.0 mmol), and 0.1015 g magnesium chloride hexahydrate (0.50 mmol) were added together to the 18 ml ethanol-water solution (v:v = 2:1) and stirred to dissolve. Heating the above solution to 75 °C for reaction for 4 h. The colorless needle-like crystals were obtained from filtrate after 25 days.
2 Experimental details
The hydrogen atoms were positioned geometrically (C–H = 0.95 Å, N–H = 0.88–0.92 Å, O–H = 0.84–0.88 Å). Their Uiso values were set to 1.2Ueq or 1.5Ueq of the parent atoms.
3 Comment
The study of the structure and properties of acylhydrazone compounds and their complexes has always been one of the priorities of coordination chemistry. 5 , 6 Because they show excellent properties such as vibrio harveyi inhibition activity, 7 turn-on fluorescent chemosensor, 8 neuritogenic activities in Neuro-2a cells, 9 and magnetic properties. 10 Some acylhydrazone compounds and their complexes have been synthesized and structurally characterized in our study group. 11 , 12 , 13 , 14 The molecular structure of the title compound is shown in figure. Our original intention was to synthesize an acylhydrazone magnesium complex, and unfortunately, magnesium ions are not involved in coordination. In the title compound, the bond lengths of C7=N3 and C6=O2 are 1.2684(19) and 1.2218(18) Å, respectively, which are shorter to C6–N2 (1.3516(18) Å) and C1–O1 (1.2551(19) Å), showing that C7=N3 and C6=O2 are expected for double bonds. The dihedral angle between two pyridine rings is 3.72°, showing that the 2-hydroxy-isonicotinic acid pyridin-4-ylmethylene-hydrazide molecule is almost coplanar. The title compound molecules form 1D chained structure by intermolecular N(1)–H(1)⋯N(4) hydrogen bonds, and the 1D chains further form a three-dimensional network structure by hydrogen bonds.
