The synthesis and spectral properties of the novel monodentate(s) coordinated thiosemicarbazide and thiosemicarbazone complexes [Fe(CO)2L(η5-C5H5)][PF6] (L = H2NNHCSNH2, cy-C5H10CNNHCSNH2 or R′R″CNNHCSNH2, R′ = R″ = Me; R′= H, R″ = Ph; R′= H, R″ = p-NO2Ph, R′= Me, R″ = p-MePh)

Synthesis and characterization of amine complexes of the cyclopentadienyliron dicarbonyl complex cation, [Cp(CO)2Fe]+

“…The cationic complexes of type, [CpFe(CO) 2 L] + (L = labile ligand) [1][2][3][4] are an important class of transition metal compounds that have been extensively utilized in synthesis [2,[4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] and catalysis [3,14,[22][23][24][25][26][27][28][29][30][31][32][33]. A particular example is the ethereal complex, [CpFe-(CO) 2 (THF)]BF 4 [34] in which the labile tetrahydrofuran (THF) is coordinated to the metal centre through the oxygen atom.…”

“…[CpFe(CO) 2 (acetone)] + is another complex with an oxygen-bonded ligand which has also been extensively used in the synthesis of both neutral and cationic complexes based on the CpFe(CO) 2 moiety [2,[5][6][7][8][9]21,40,41].…”

Synthesis, characterization, structural features and cytotoxicity of innovative zinc(II) complex derived from ONS-donor thio-Schiff base of acyl pyrazolone

“…Reaction between ketones (or aldehydes) and a thiosemicarbazide that gives thiosemicarbazones and which are called thio-Schiff and owing to their good binding capacity to metal they are very suitable in coordination chemistry [7]. Tautomer thione (-C=S) and thiol (-C-SH) forms ( Figure 1) of thiosemicarbazone act as neutral or anionic bidentate ligands from the donor sites of azomethine N and S(thione/thiol) [8,9]. Their Zn (II) complexes show prospective fluorescence properties [10,11].…”
