Ö Z E T K ompleksin kristal yapısı [Mg(H 2 O) 6 ](C 4 H 4 NO 4 S) 2 , 296 K'de tayin edildi. Moleküler Kristal yapının birim hücre parametreleri a=6.9404 Å, b=8.5775 Å, c=8.7200 Å, α=68.564°, β=78.640°, γ=81.260° ve Z=1 olarak saptanmıştır. Kompleks merkezi simetrik triklinik yapıda kristallenmiş olup uzay grubu P-1'dir. Her bir Mg(II) iyonu altı mol su ligandının O atomları tarafından koordine edilmiştir. Kristal yapıda anyonlar ve katyonlar O-H···O ve O-H···N etkileşimleriyle üç boyutlu yapıyı oluştururlar. İlave olarak yoğunluk fonksiyonel teori (DFT) (B3LYP) yönteminin 6-31G temel setleri kullanılarak elde edilen hesaplanmış sonuçlarla deneysel X-ışınları kırınım sonuçları kıyaslanarak moleküler yapı oluşturulmuştur. Moleküler elektrostatik potansiyel, frontier moleküler orbitaller ve IR spektrumu DFT yöntemi kullanılarak hesaplanmıştır.

A B S T R A C TT he crystal structure of the complex, [Mg(H 2 O) 6 ](C 4 H 4 NO 4 S) 2 , was determined at 296 K. The unit cell parameters of the crystal structure are a=6.9404 Å, b=8.5775 Å, c=8.7200 Å, α=68.564°, β=78.640°, γ=81.260° and Z=1. The complex crystallizes in the centrosymmetric triclinic space group P-1. The Mg(II) ion is coordinated by six O atoms from six aqua ligands and in the crystal structure, the anions and cations are linked with three dimensions via O-H···O and O-H···N interactions. In addition to the structure which was obtained by X-ray diffraction technique, the theoretical structure was calculated by using density functional theory (B3LYP) with the 6-31G basis sets. The molecular electrostatic potential, frontier molecular orbitals and theoretical IR studies were calculated by using DFT method. Besides, the experimental IR spectrum and thermal analysis were investigated for the complex.

“…The resulting solution was stirred for five hours in a magnetic stirrer heated to approximately 60 °C. The decreasing solution due to heat was continuously supplemented to the total amount of initial solution [29][30][31]. After mixing, the reaction vessel was closed with parafilm and allowed to crystallize at room temperature in a dark environment.…”

In this study, Mn doped complexes were produced and used as an interfacial layer in Au/Mn-complex/n-Si structure. For this, metal complex was prepared and added with its material. For this, a mixed ligand complex was prepared and dopped with manganese. The morphological investigations of these structures was fulfilled by using an Atomic Force Microscope. The analyzes showed that relatively smooth and well ordered surfaces. The fabricated structured were characterized using capacitance-voltage (C-V) and conductance-voltage (G/w-V).

“…[18][19][20][21][22][23] The chemical and structural behavior of coordination compounds can be adjusted by the same operation. [24][25][26][27][28] Metal and semiconductor contacts are important for electronic devices because they can be ohmic or metallic contact at the same time depending on work function differences of metal and semiconductor. [29][30][31] Sometimes an insulator or metal oxide interlayer can be inserted between metal and semiconductor to control charge conduction and stop leakage current or electrostatic charge generation.…”

Cd and Co metal centered nicotinamide/nicotinic acid complexes were synthesized by chemical reactions. The complexes were characterized by thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT‐IR), powder X‐ray diffractometer (P‐XRD), ultraviolet–visible (UV–Vis) spectrometer, and scanning electron microscopy (SEM) with energy dispersive X‐ray (EDX) detector. The complexes were used as interfacial layers in between Al and p‐Si to fabricate Al/Cd‐complex/p‐Si and Al/Co‐complex/p‐Si metal semiconductor devices. The devices were characterized by current–voltage (I‐V) and current‐time (I‐t) measurements under dark and various light power intensities. The ideality factor, barrier height, and series resistance values were extracted from I‐V measurements and discussed in detail by various techniques. The I‐t measurements were used to derive various detector parameters such as responsivity, photosensitivity, and specific detectivity for various power values and wavelength regions. The devices exhibited good photodiode and photodetector performance according to results, and they can be improved for optoelectronic applications.
