Coordination compounds of chromium(III) with semicarbazones and thiosemicarbazones of heterocyclic aldehydes

Complexation Behavior of Newly Synthesized Schiff Base N-(4-Methoxyphenyl-4\-Cyanobenzilidene) as Corrosion Inhibition

“…Ali M. HASSAN, et alazomethine nitrogen in all the complexes[24]. The Ni II Schiff base complex spectrum displays absorption band at 445 nm owing 3 T1→ 1 T2(F) transition and suggesting a tetrahedral geometry, The tetrahedral geometry is confirm by measured magnetic moment (μeff=3.47 B.M) which is harmony with the reported value,μeff=3.47 B.M, for tetrahedral complex Ni.…”

“…The FT-IR spectral data for this complex show in (Fig. 1) [15]. The presence band at 2221 cm -1 assignable to ν(CN) and peaks at (3650-3200) cm -1 are attributable to coordinated water molecules [16].…”

“…We have previously reported the synthesis and characterization of complexes obtained from 3-(2-furyl) 2-propenal semicarbazone (FASC) [1], 2-furaldehyde semicarbazone (FSC) and 5-methyl-(2-furaldehyde) semicarbazone (MFSC) [2]. The co-ordinating properties of various semicarbazones have also been studied [3][4][5] as well as those of many thiosemicarbazones [6][7][8][9][10][11][12][13][14]. In this paper, we present the synthesis and characterization of new metal complexes of 2-furfural 4-phenyl semicarbazone FPSC (Figure 1) and cobalt(II), nickel(II), copper(II) and cadmium(II) chlorides and bromides.…”

Antimicrobial and Antifertility Activities of Newly Synthesized Triorganosilicon(iv) Complexes

“…A new band at around 400 nm due to 440 Brought to you by | Purdue University Libraries Authenticated Download Date | 6/24/15 1:39 PM η-π* electronic transitions of the azomethine group is observed in the spectra of silicon complexes. This suggests the formation of azomethine grouping on complexation and thus isomerization of the benzothiazolines into the Schiff base form in presence of silicon atom 14 .…”
