The bis-(benzimidazol-1-yl)methane mol-ecule of the title compound, C(15)H(12)N(4)·2H(2)O, displays a trans conformation with a twofold axis running through the methylene C atom. Two adjacent water mol-ecules are bonded to this mol-ecule through O-H⋯N hydrogen bonds, forming a trimer. Adjacent trimers are connected together via C-H⋯O inter-actions, forming a chain running along the b-axis direc...

this study prepared new edible composite film by blending kefiran with whey protein. the film-forming solutions used different ratios of kefiran to whey protein (70/30, 50/50, 30/70, 10/90) and were cast at room temperature. the effects of the addition of whey protein on the physical, mechanical and water-vapor permeability (wvp) properties of the film were investigated. it was found that an in...

The complete molecule of the title compound, C(17)H(16)O(4), is generated by crystallographic twofold symmetry, with the central C atom lying on the rotation axis and a dihedral angle between the benzene rings of 81.9 (2)°. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonding between carboxyl groups, forming one-dimensional supra-molecular chains.

In the title compound, C(13)H(10)BrNO, the dihedral angle between the benzene rings is 35.20 (8)°. In the crystal, mol-ecules are linked by O-H⋯N hydrogen bonds, forming a zigzag chain along the a axis. A weak C-H⋯π inter-action is observed between the chains.

In the title compound, C14H10N4O6S, the indazole ring system is almost perpendicular to the tosyl ring, as indicated by the dihedral angle of 89.40 (9)° between their planes. The dihedral angles between the indazole system and the nitro groups are 57.0 (3) and 31.9 (3)°. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, forming chains running along [100].

In the title compound, C(12)H(16)N(2)O, the dihedral angle between the pyridine ring and C/O/N plane is 22.93 (7)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules, forming extended chains along [001]. π-π inter-actions between inversion-related pyridine rings [centroid-centroid distance = 3.825 (2)Å] are also observed.

Predicting the glass-transition temperatures (Tg) of glass-forming polymers is critical importance as it governs thermophysical properties polymeric materials. The cheminformatics approaches based on machine learning algorithms are becoming very useful in predicting quantitative relationships between key molecular descriptors and various physical In this work, we developed a modeling framework ...

The article considers the approach to digital transformation of aviation industry in terms organizing interaction supply chain participants involving air transport based on platform. Digital is considered not only as a tool information interaction, but also business model that creates value by uniting consumers and producers goods services. There was performed statistical analysis indicators ch...

Yanking the chain: a general method for the preparation of colloidal analogues of polymer chains was developed. The flexibility of these chains can be tuned by applying electric fields in combination with their subjection to simple linkage-forming procedures.

In the mol-ecular structure of the title compound, C(16)H(17)NO, the two aromatic rings are close to orthogonal to each other [dihedral angle 78.8 (1)°], while the central -NH-C(=O)- amide core is nearly coplanar with the benzoyl ring, forming a dihedral angle of 3.5 (2)°. Inter-molecular N-H⋯O hydrogen bonds in the crystal structure link the mol-ecules into infinite chains running along the c ...
