“…Hydrazones are an emerging class of materials, which have been demonstrated to possess awide range of biological and pharmaceutical activities such as antimicrobial, anti-convulsant, antifungal,anticancer, antitubercular, antiviral,antibacterial, and antioxidant activities [1][2][3][4][5][6][7][8].M eanwhile,h ydrazones have also interesting properties because of the presence of several coordinations ites,a nd thus theirm etal complexes are important for their possible biological applications [9].T he thiazole ring is present in various biologically active molecules. Thiazoles and their derivatives possessa ctivities such as antitumor, antiviral, and antibacterial [10][11][12].…”

Source of materialThe title compound was obtained from 2-amin-3-chloropyridine according to the literature method [14]. Single crystals suitable for X-ray diffraction were obtained by crystallization of the title compound from methanol. Experimental detailsAll of the non-hydrogen atoms were refined anisotropically. The hydrogen atoms were assigned with common isotropic displacement factors U iso (H) = 1.2U eq (N and pyridine C), or U iso (H) = 1.5U eq (methyl C) and included in the final refinement by using geometrical restraints, with C-H = 0.93 Å (pyridine) or C-H = 0.96 Å (methyl), and N-H = 0.86 Å. 12]. In this paper we report the synthesis and crystal structure of a novel thiazolehyrazone compound. The asymmetric unit contains one molecule of the title compound, which is constructed by the pyridinethiazole moiety, the hydrazone linker, and the bimethyl moiety. Discussion
