The cocrystal 10-(2-methyl-4-phenyl-1H-inden-6-yl)-10H-phenothiazine–10-(2-methyl-7-phenyl-1H-inden-5-yl)-10H-phenothiazine (0.54/0.46)
The title compound, 0.535C28H21NS.0.465C28H21NS, was synthesized by palladium-catalysed amination. The structure is composed of two isomeric molecules, viz. 10-(2-methyl-4-phenyl-1H-inden-6-yl)-10H-phenothiazine, and 10-(2-methyl-7-phenyl-1H-inden-5-yl)-10H-phenothiazine, in the refined ratio 0.535 (12):0.465 (12). The isomers differ by the localization of the double bond in the cyclopentadiene ring. There are two sites in the structure that are occupied by the isomers. The respective isomers are occupationally disordered in each site, the refined proportions being 0.640 (6):0.360 (6) and 0.43 (1):0.57 (1). Moreover, each isomeric molecule is chiral; due to the crystallographic centres of symmetry, the molecules are also present in enantiomeric pairs. The crystal structure is stabilized by weak π–π [C⋯C = 3.389 (2) Å] interactions
RuDaCoP: The Dataset for Smartphone-based Intellectual Pedestrian Navigation
This paper presents the large and diverse dataset for development of
smartphone-based pedestrian navigation algorithms. This dataset consists of
about 1200 sets of inertial measurements from sensors of several smartphones.
The measurements are collected while walking through different trajectories up
to 10 minutes long. The data are accompanied by the high accuracy ground truth
collected with two foot-mounted inertial measurement units and post-processed
by the presented algorithms. The dataset suits both for training of
intellectual pedestrian navigation algorithms based on learning techniques and
for development of pedestrian navigation algorithms based on classical
approaches. The dataset is accessible at http://gartseev.ru/projects/ipin2019
