Crystal structure of bis(isothiocyanato)[2,6-diacetylpyridine bis(4-hydroxybenzoylhydrazone)]Fe(III) Chloride bis(dimethylformamide) solvate

The crystal structure of title compound (Fe[(C25H21N7O4S2)] · 4(C3NOH7), where C3NOH7 is dimethylformamide, DMF) was determined by the X-ray diffraction method. This compound crystallizes in the monoclinic C2/c space group, Z = 4. Unit cell parameters are: a = 13.6080(5), b = 17.6375(7), c = 19.5571(6) Å, β = 108.753(2)°. The N-H...O and O-H...O interactions stabilize the molecules in the lattice. The structure contains also the solvent dimethylformamide molecules, which are connected with intermoleculer hydrogen bond. The O atoms of DMF molecules take place as acceptor atoms.

4-But-oxy-N'-[1-(4-methyl-phen-yl)ethyl-idene]benzohydrazide.

The molecule of the title compound, C20H24N2O2, exists in a trans conformation with respect to the C=N bond. The dihedral angle between the benzene rings is 79.0 (1)°. In the crystal, N—H⋯O hydrogen bonds link the molecules into chains propagating in [001]. Two weak C—H⋯O interactions also occur.

[Bis­(di­phenyl­phosphino)­methane][1,3-bis­(di­phenyl­phosphino)­propane]­platinum(II) dibromide

The asymmetric unit of the title compound, [Pt(C(25)H(22)P(2))(C(27)H(26)P(2))]Br(2) or [Pt(dppm)(dppp)]Br(2), where dppm is bis(diphenylphosphino)methane and dppp is 1,3-bis(diphenylphosphino)propane, consists of a discrete [Pt(dppm)(dppp)](2+) cation and two Br(-) anions at van der Waals distances. This is the first reported platinum(II) complex containing both dppm and dppp ligands. Noticeable features are that the coordination of platinum by the differing dppm and dppp ligands produces a distorted coordination geometry with differing ligand bite angles (and to a lesser extent bond distances), and that the strain induced by the formation of the four-membered dppm chelate ring has a marked effect upon the bond angles at the P atoms of this ligand.

Üniversitelerde Bilişim Teknolojileri Risk Yönetimi Başarısını Etkileyen Faktörler Üzerine Nitel Bir Araştırma: Ankara İli Örneği

In this study, the indicators and factors affecting IT risk management success of state universities in Ankara were investigated. In this research, qualitative research method was used. A semi-structured interview technique was used to collect qualitative data of the study. The participants were seven computer center administrators working in state universities in Ankara. Data obtained from this study were analyzed by using descriptive analyses techniques. After analyzing the data, the indicators effecting IT risk management success were determined and classified under institutional, human, environmental and technological factors. Results were compared with findings of previous studies and recommendations were presented to researchers and practitioners

4-Hydroxy-N′-[(1E)-1-(4-methylphenyl)ethylidene]benzohydrazide: Synthesis, crystal structure, and spectroscopic studies

The titled compound has been synthesized by reaction of 4′-methylacetophenon with 4-hydrox-ybenzohydrazide in presence of catalytic amount of glacial acetic acid. The compound is characterized by elemental analysis, IR, 1H NMR, 13C NMR and UV-visible spectra. The crystal structure was determined by X-ray diffraction method. Both X-ray data and NMR spectra indicate that the molecule exists in a trans configuration with respect to the C=N bond. The observation of strong ν(C=O) peak in IR spectra of the aroylhydrazone compound suggests that it is in keto form in solid state. X-ray diffraction results confirm this suggestion. In the crystal structure, there are N-H...O and O-H...O hydrogen bonds and weak C-H...π interaction.
