Synthesis and X-ray structural studies of Cd(II) and Ni(II) complexes of 5-(4-methoxy phenyl), 5-(2-pyridyl) and 5-(2-methoxy phenyl)-1,3,4-oxadiazole-2-thione

5-(2-Methylfuran-3-yl)-N-phenyl-1,3,4-oxadiazol-2-amine

“…The coordination chemistry of nitrogen-oxygen containing heterocyclic ligands such as 1,3,4-oxadiazoles and their derivatives containing the HNCO moiety is an emerging and rapidly developing area of research (Wang et al, 2007;Foroumadi et al, 2001;Bharty et al, 2012). 1,3,4-Oxadiazole derivatives have also been the subject of extensive study in the recent years because of their diverse biological activities (Luo et al, 2016;Aboraia et al, 2006;El-Emam et al, 2004;Bharty et al, 2015).…”

Crystal structure ofN′-[bis(ethylsulfanyl)methylidene]-2-hydroxy-4-methoxybenzohydrazide

“…For their biological properties, see: Bharti et al (2000). For cyclization of potassium salts of N-(aroyl)hydrazine carbodithioates, see: Singh et al (2008Singh et al ( , 2009; Bharty et al (2012). For bidentate, tridentate and multidentate esters, see: Wang et al (2002); Tarafder et al (2000); Ali et al (2001).…”

“…They form large number of metal complexes with novel structural features (Ali et al, 2008;Singh et al, 2010;Singh et al, 2012). The S-alkyl/aryl esters derived from potassium salts of Naroylhydrazine carbodithioates have been found to be more stable towardscyclization (Singh et al, 2008) and form 1,3,4oxadiazole-2-thiones in the presence of acid or base (Singh et al, 2009;Bharty et al, 2012). The above esters behave as bidentate, tridentate or multidentate chelating agents with hetero donor atoms (Wang et al, 2002;Tarafder et al, 2000;Ali et al, 2001).…”

N′-[Bis(methylsulfanyl)methylidene]-2-methoxybenzohydrazide

“…The S-alkyl/aryl esters exhibit efficient capacity for coordination with metals to form complexes (Ali et al, 2008;Singh et al, 2010Singh et al, , 2012. The S-alkyl/aryl esters derived from potassium salts of N-aroylhydrazinecarbodithioates have been found to be more stable towards cyclization compared to potassium N-aroylhydrazinecarbodithioates and form stable complexes with transition metal ions (Singh et al, 2009;Bharty et al, 2012).…”
