A polynuclear and two dinuclear copper(II) Schiff base complexes: Synthesis, characterization, self-assembly, magnetic property and DFT study

Diethylaminophenyl-based Schiff base Cu(ii) and V(iv) complexes: experimental and theoretical studies and cytotoxicity assays

“…These transitions confirm the square planar geometry of complex (2), typical of Cu(II) complexes with Schiff bases. [36][37][38] The broad band observed in the spectrum of (3) between 550 and 700 nm are assigned to the d-d transition of the VO(IV) complex.…”

Experimental and theoretical study of novel amino‐functionalized P(V) coordination compounds suggested as inhibitor of MProof SARS‐COV‐2 by molecular docking study

“…Form HS analysis, the H … H and H … C/C … H contacts and then, H … O/O … H and H … N/N … H (for 1 and 2 ) or H … Cl/Cl … H and H … N/N … H (for 3 ) are contacts with the most contribution related to the total HS. As it is seen, the H … O/O … H contact dominate the H … N/N … H for the metal‐phosphramide complexes 1 and 2 , whereas in the Salen complexes, [ 63,69 ] the H … N/N … H is maximum than the H … O/O … H. This can be attributed to the uncoordinated phosphoryl oxygen atoms in 1 and 2 which are involved in the N―H … O hydrogen bonding, where in the phosphoramide complexes with the coordinated phosphoryl oxygen atoms, [ 25 ] similarly the H … N/N … H input is larger than the H … O/O … H.…”

Synthesis, structures and magnetic properties of octahedral Co(III) complexes of heteroaromatic hydrazones with tetraisothiocyanato Co(II) anions

“…IR spectra were recorded on a Nicolet 6700 FT-IR spectrometer using the ATR technique in the region 4000−400 cm −1 (vsvery strong, s-strong, m-medium, w-weak, bs -broad signal). 1 H and 13 C NMR spectra were recorded on Bruker Avance 500 spectrometer ( 1 H at 500 MHz; 13 C at 125 MHz) at room temperature using TMS as internal standard in DMSO-d 6 (numbering of atoms according scheme S1).…”

“…There is a considerable interest in design and synthesis of Schiff bases complexes containing pseudohalide ligands due to their structural diversity, magnetic and spectral properties, as well as biological activity [1][2][3][4][5][6][7][8][9][10][11][12]. Thiocyanate is an ambidentate pseudohalide ligand, which can be coordinated through nitrogen or sulfur donor atom as monodentate or as a bridge between metal centers [13].…”
