The title compound was synthesized by mixing 0.077 g (0.3 mmol) L4 ((E)-1,5-dimethyl-2-phenyl-4-((pyridin-4-ylmethylene)amino)-1H-pyrazol-3(2H)-one, which was prepared according to the literature [4]), 0.075 g (0.25 mmol) Zn(NO3)2 ⋅ 6H2O, 5 mL absolute ethyl alcohol and 1 mL dichloromethane in a reaction kettle flask. Then the reaction kettle flask was placed in an oven at 90 °C. After 7 days, red granular crystals were separated with 20.25% yield.

Comment
At present, the water (solvent) thermal synthesis method has been successfully applied to the synthesis of some metal organic frameworks with unique structures and special properties. The reaction mechanism follows the liquid nucleation mode [5]. Water (solvent) thermal synthesis reactions make it possible to synthesize some novel materials with special functions or unique structures by using high-temperature aqueous solutions or solvents as the reaction medium for some reactions which will not proceed at room temperature [6].
Some metal schiff base complexes have special properties and applications [7], [8]. Herein, the complexes of Zn(II) with pyridine-4-carboxaldehyde 4-aminoantipyrine (L4) was synthesized by water (solvent) thermal synthesis. The asymmetric unit of the title structure consists of one Zn(II) atom, two pyridine nitrogen atoms of two L4 ligands, two nitrate ions and one water molecule. In the complex, the center Zn atom forms a distorted square-pyramidal coordination sphere. The coordination donor atoms come from two oxygen atoms of two separated nitrate anions and two pyridine nitrogen atoms of two L4 ligands, and the water O7 atom resides on the apical position. (cf. the figure). The angle N(5)—Zn(1)—N(1) is 173.32(13)°. The bond lengths of Zn(1)—N(1) and Zn(1)—N(5) are by chance both 2.127(3) Å, which are different from that referred in other reports [9]. The bond length of Zn(1)—O(1) is 2.172(3) Å, the bond length of Zn(1)—O(4) is 2.188(4) Å, the length of Zn(1)—O(7) is 2.023(3) Å. The bond lengths of Zn(1)—O(1) and Zn(1)—O(4) are almost the same. Bond lengths and bond angles of ligand L4 are within the normal range [10]. A different coordination for two nitrato ligands is not unusual [11]. A structurally directly related Ni(II) complex is known for more than one decade [12].
