“…The peak value at 3253 cm −1 was attributed to the ν(O–H) stretching band of HL 1 , whereas complexes 1 and 2 showed the expected absorption at 3263 and 3409 cm −1 , indicating the existence of O–H group from oxime. [ 45 ] Appearance of new weak bands in the far‐IR spectra of two complexes were assigned to ν(M–O) and ν(M–N) at 488, 454 cm −1 and 545, 540 cm −1 , respectively. The consequences were consistent with these obtained by X‐ray diffraction.…”

The quinazoline-type ligand 2-(4-diethylamino-2-hydroxyphenyl)-4-methyl-1,-2-dihydroquinazoline 3-oxide (HL 1 ; H is the deprotonatable hydrogen) was prepared. Two 2-D supramolecular complexes [Cu 2 (L 2) 2 (NO 3) 2 ] (1) and [Ni 2 (L 2) 2 (CH 3 COO) 2 ] (2) (L 2 = 1-(2-{[(E)-(4-diethylamino-2-hydroxybenzylidene] amino} phenyl)ethanone oxime) were synthesized using HL 1 and characterized by elemental analysis, spectroscopic methods, and single-crystal X-ray diffraction studies. It revealed that 1 had coordinated two nitrate ions whereas 2 had acetate ions. In the crystal structures, six-coordinated Cu (II) complex 1 formed an infinite 2-D and X-shaped 3-D supramolecular frameworks. Simultaneously, Ni (II) complex 2 assembled into wavy 2-D networks. Furthermore, electrochemical properties and antimicrobial activities of all compounds were as well investigated. Afterwards, the electrophilic and nucleophilic attack sites identified by electrostatic potential (ESP) calculations confirmed that hydrogen bonds were observed in the optimized structure of the crystal, and the closest contact between the active atoms of both complexes was confirmed through Hirshfeld surface analysis and time-dependent density functional theory (TD-DFT) calculations.

Bir ONNO tipi Schiff bazı olan bis-N;N'(salisiliden)-1,3-propandiamin (LH2) ve ONO tipi Schiff bazı olan N(2-hidroksi)salisillaldimin (SAPH2) kullanılarak beş farklı Nikel (II) kompleksi NH3 veya amin varlığında hazırlandı ve bu komplekslerin havada termal bozunması ile NiO nanoparçacıkları elde edildi. Hazırlanan kompleksler ve Schiff bazları, element analizi, IR spektroskopisi, Termogravimetri (TG), 1HNMR ve 13CNMR spektroskopisi, Kütle Spektrometrisi (MS), Atomik absorpsiyon spektrometrisi (AAS), ve Taramalı Elektron Mikroskobu (SEM) ile karakterize edildi. Elde edilen nanoparçacık NiO malzemenin yüzey alanı Brunauer-Emmett-Teller (BET) yöntemi ile ölçüldü. NiO nanoparçacıklarının termal bozunma ürünleri XRD ve SEM teknikleri ile incelendi. SEM incelemeleri, hazırlanan iki kompleksin çözünürlüğünün çok az olması nedeniyle nanopartiküller halinde çöktüğünü gösterdi. Bu sebepten dolayı çözünmeyen komplekslerin termal bozunma sonucunda NiO nanoparçacıklarına dönüştüğü gözlemlendi.

Two novel N ∧ O-type Schiff base ligands and the corresponding Co(II) complexes are reported. Thermogravimetric analysis indicated that the complexes are potential molecular precursors for the fabrication of cobalt and cobalt-containing nanomaterials. The significant difference in the thermal decomposition profiles is recognized as an influence of structural differences on the complexes. Thus, the complexes were thermally decomposed using the melt and hot injection methods to examine the properties of the obtained cobalt and cobalt sulfide nanoparticles, respectively. The reaction parameters employed during the fabrication processes, in addition to structural differences, influenced the morphological and crystallographic phases and magnetic properties of the synthesized nanoparticles. We have investigated the morphological properties and the crystallographic phase compositions of the nanoparticles by various electron microscopy and diffraction techniques, as well as energy-dispersive X-ray spectroscopy. The melt reactions produced phase-pure cobalt nanoparticles, which exhibit ferromagnetic behavior. The hot injection method utilized 1dodecanethiol (DDT) as both sulfur source and capping agent. We indexed the DDT-capped cobalt sulfide nanoparticles to cubic Co 9 S 8 and Co 3 S 4 phases using powder X-ray diffraction, high-resolution transmission electron microscopy imaging, and selected area electron diffraction. The crystallite sizes for Co 9 S 8 and Co 3 S 4 nanoparticles, based on the Scherrer equation, were 12.4 nm and 14.1 nm, respectively. We find significant differences in the magnetic properties, attributed to nonmagnetic inclusions and vacancies due to the presence of S atoms.
