“…The distortion is mainly due to the rigidity of the five-membered N(1)-Sn(1)-N(2) chelate rings, with angles of 73.15 (12)°and 73.43(9)°(average value) in 3 and 4, respectively.…”

“…Several reviews dealing with the synthesis, structural behaviour and biological applications of these materials have been published [3]. In particular, complexes with Schiff bases derived from amino acids [4][5][6] and ONO and NNO dianionic terdentate Schiff bases have been widely reported [6][7][8][9][10][11][12]. Recently, the synthesis and toxicological activity of organotin(IV) compounds with a sulfonamide imine ligand have been also described, although crystal structures for these compounds were not reported [13].…”

Diorganotin(IV) complexes with 2-furancarboxylic acid hydrazone derivative of benzoylacetone: Synthesis, X-ray structure, antibacterial activity, DNA cleavage and molecular docking

“…Recently these compounds have been used in new contexts as in cancer chemotherapy [22,23]. In view of a few reports on organotin(IV) complexes of hydrazones derived from 1,3-diketones [24][25][26][27][28], it was considered worthwhile to investigate the synthesis, structural aspects and biological properties of hydrazonic derivatives of 1,3-diketones and their organotin complexes. In the present paper, 2-furancarboxylic acid hydrazone derivative of benzoyl acetone and its dimethyl-and diphenyltin complexes have been synthesized.…”

Synthesis, Crystal Structure and Bioactivities of a Novel Propeller Shaped Manganese Complex with the Ligand N′‐Benzylidenesalicylhydrazide

“…[11][12][13] In particular, complexes with Schiff bases derived from amino acids [14][15][16] and ONO and NNO tridentate dianionic Schiff bases have been widely reported. [17][18][19][20] This type of ligand typically acts as a multidentate planar chelating agent coordinating through the phenolic and amide oxygens and imine nitrogen.…”
