Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , COA of Formula: C17H15NO3, 4803-74-1, Name is 5,6-Dimethoxy-2-(pyridin-4-ylmethylene)-2,3-dihydro-1H-inden-1-one, molecular formula is C17H15NO3, belongs to pyridine-derivatives compound. In a document, author is Sedykh, Alexander E., introduce the new discover.
The crystal structure of the triclinic polymorph of 1,4-bis([2,2 ‘:6 ‘,2 ”-terpyricim]-4 ‘-yl)benzene
The title triclinic polymorph (Form I) of 1,4-bis([2,2′:6′,2 ”-terpyridin]-4′-yl)-benzene, C36H24N6, was formed in the presence of the Lewis acid yttrium trichloride in an attempt to obtain a coordination compound. The crystal structure of the orthorhombic polymorph (Form II), has been described previously [Fernandes et al. (2010). Acta Cryst. E66, 03241-03242]. The asymmetric unit of Form I consists of half a molecule, the whole molecule being generated by inversion symmetry with the central benzene ring being located about a crystallographic centre of symmetry. The side pyridine rings of the 2,2′:6’,2 ”-terpyridine (terpy) unit are rotated slightly with respect to the central pyridine ring, with dihedral angles of 8.91 (8) and 10.41 (8)degrees. Opposite central pyridine rings are coplanar by symmetry, and the angle between them and the central benzene ring is 49.98 (8)degrees. The N atoms of the pyridine rings inside the terpy entities, N center dot center dot center dot lie in trans-trans positions. In the crystal, molecules are linked by C-H center dot center dot center dot pi and offset pi-pi interactions [intercentroid distances are 3.6421 (16) and 3.7813 (16) angstrom], forming a three-dimensional structure.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 4803-74-1. COA of Formula: C17H15NO3.
