[μ-N1,N2-Bis(pyridin-2-yl)hydrazine-1,2-dicarbothioamidato]bis[chloridocopper(II)]

“…The C6-N distances of 1.311 (3)-1.366 (3) Å and the N3-N3A distance of 1.399 (3) Å are intermediate between formal single and double bonds, pointing to extensive electron delocalization over the entire ligand skeleton. This agrees well with the same distances observed in related compounds (Wang et al, 2011;Yamin & Yusof, 2003;Akinchan et al, 2002).…”

“…For the biological activity of thiosemicarbazides and their metal complexes, see: West et al (1993). For related structures, see: Wang et al (2011); Yamin & Yusof (2003); Akinchan et al (2002). For the synthesis of the ligand, see: Szecsenyi et al (2006).…”

The synthesis, characterization and antimicrobial activity of N,N′-bis(2-thiophenecarboxamido)-1,3-diaminopropane and N,N′-bis (2-furancarboxamido)-1,3-diaminopropane and their Cu(II), Zn(II), Co(III) complexes

“…13 C-NMR spectral data of amides and their Zn(II) complexes are collected in Table 3. Amide carbonyl, C(5) has the highest chemical shifts and observed between 159.05 and 163.45 ppm in aromatic field for these compounds [14]. Each half of symmetric amide ligands has the same chemical shifts in NMR spectra.…”

“…Amide I band, which consists mainly of C=O vibration (m C=O ) are observed at 1630-1650 cm -1 . Amide II band, which arises from m C-N as well as d N-H are coupled to one another and observed at 1550-1575 cm -1 [13,14]. Amides Thermal studies Thermal behavior of complexes was determined in nitrogen atmosphere (20 ml min -1 ) with a heating rate of 10°C min -1 in the temperature range 30-400°C.…”

Bacteriostatic activities ofN-substituted tris-thioureas bearing amino acid and aniline substituents

“…Significant absorptions at 1183-1059 cm 1 were attributed to v(C-N) and furthermore proved that the reaction was complete. 11,12 The chemical structures of 1-9 were further confirmed by 1 H and 13 C NMR spectroscopy, which exhibited resonances expected for the target compounds. The existence of thiourea moieties in 1-9 was proven by the appearance of two NH resonances at δ = 12.62-11.79.…”
