Crystal structure and Hirshfeld surface analysis of (2Z)-N,N-dimethyl-2-(pentafluorophenyl)-2-(2-phenylhydrazin-1-ylidene)acetamide

Abstract

In the title compound, C16H12F5N3O, the dihedral angle between the aromatic rings is 31.84 (8)°. In the crystal, the molecules are linked into dimers possessing crystallographic twofold symmetry by pairwise N—H...O hydrogen bonds and weak C—H...O hydrogen bonds and aromatic π–π stacking interactions link the dimers into a three-dimensional network. A Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from F...H/H...F (41.1%), H...H (21.8%), C...H/H...C (9.7%) C...C (7.1%) and O...H/H...O (7.1%) contacts. The contribution of some disordered solvent to the scattering was removed using the SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9–18] in PLATON. The solvent contribution was not included in the reported molecular weight and density.

Features of forecasting abnormally high reservoir pressures when drilling wells in areas of south-western Turkmenistan

“…It should be noted that inaccurate high reservoir pressure predictions can have significant implications across economic, environmental, and safety domains. Economically, such inaccuracies can lead to unexpected drilling challenges, increasing costs due to the need for more equipment, materials, and extended operational time to manage high-pressure formations (27)(28)(29)(30) . This also causes production delays, impacting project timelines and potentially leading to financial losses from reduced productivity, along with a misallocation of resources as operational plans and budgets need adjustment.…”
