The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 2-Furoic hydrazide(SMILESS: O=C(C1=CC=CO1)NN,cas:3326-71-4) is researched.Synthetic Route of C18H20N2O12. The article 《Synthesis, crystal structures, and characterization of three zinc complexs with different acylhydrazone-type schiff base ligands》 in relation to this compound, is published in Wuji Huaxue Xuebao. Let’s take a look at the latest research on this compound (cas:3326-71-4).
Three zinc complexes, namely [Zn(Lss)(phen)(DMF)] (1), {[Zn (HLdis)]2·2CH3OH}n (2) and [Zn(Baf)2]·CH3OH (3), formed from different acylhydrazone-type Schiff base ligands were synthesized by using different methods, and the compounds were characterized by IR, UV-Vis spectra and TGA. The X-ray diffraction analyses revealed that 1 and 3 crystallized in the triclinic space group P1̅ while 2 in monoclinic system space group P21/n. In 1 and 3, coordination number of the Zn (II) was six, and the centric atom located in a distorted octahedron geometry, while in 2 Zn (II) was five-coordination in a distorted square-pyramidal geometry. The precursor of 3 was pyrazoline derivative with the formula C15H14N2O3 (Pzl) crystallizing in monoclinic system space group P21/c. Due to the coordination of Zn (II) causing the intramol. rearrangement of Pzl, the ring open product HBaf in the form of an acylhydrazone structure coordinated with Zn (II) to form complex 3.
