catena-Poly[[trimethyltin(IV)]-μ-2-(2-chlorophenyl)acetato]
In the title polymeric coordination compound, [Sn(CH3)3(C8H6ClO2)]n, the Sn atoms exhibit a distorted trigonal-bipyramidal geometry with the carboxylate O atoms of the 2-chlorophenylacetato ligands in axial positions and with the equatorial sites occupied by the three methyl groups. Adjacent Sn atoms are bridged by coordination to the two O atoms of each 2-chlorophenylacetato ligand, forming a chain structure

Examining Associations of Environmental Characteristics with Recreational Cycling Behaviour by Street-Level Strava Data
Policymakers pay much attention to effectively increasing frequency of people’s cycling in
the context of developing sustainable and green cities. Investigating associations of environmental characteristics and cycling behaviour could offer implications for changing urban infrastructure aiming at encouraging active travel. However, earlier examinations of associations between environmental characteristics and active travel behaviour are limited by low spatial granularity and coverage of traditional data. Crowdsourced geographic information offers an opportunity to determine the fine-grained travel patterns of people. Particularly, Strava Metro data offer a good opportunity for studies of recreational cycling behaviour as they can offer hourly, daily or annual cycling volumes with different purposes (commuting or recreational) in each street across a city. Therefore, in this study,
we utilised Strava Metro data for investigating associations between environmental characteristics and recreational cycling behaviour at a large spatial scale (street level). In this study, we took account of population density, employment density, road length, road connectivity, proximity to public transit services, land use mix, proximity to green space, volume of motor vehicles and traffic accidents in an empirical investigation over Glasgow. Empirical results reveal that Strava cyclists are more likely to cycle for recreation on streets with short length, large connectivity or low volume of motor vehicles or on streets surrounded by residential land
(E)-2-Methoxy-6-(thiazol-2-yliminomethyl)phenol
The title compound, C11H10N2O2S, displays an E configuration about the C=N bond. The mean planes of the thiazole and benzene rings make a dihedral angle of 9.32 (18)°. Intramolecular O—H⋯N hydrogen bonds are found in the crystal structure
3-Ethoxy-2-(1,3-thiazol-2-yl)isoindolin-1-one
In the title compound, C13H12N2O2S, the dihedral angles between the isoindolone ring system and the thiazole ring and the ethoxy group are 6.50 (11) and 89.0 (2)°, respectively
3,3′-Oxybi[isobenzofuran-1(3H)-one]
The title compound, C16H10O5, consists of two isobenzofuran-1(3H)-one moieties which are linked by a bridging O atom. The two halves of the molecule display approximate non-crystallographic mirror symmetry. The dihedral angle between the two isobenzofuran-1(3H)-one ring systems is 53.18 (6) Å. Two chiral carbon centres are observed in the compound, but their absolute configurations could not be determined. In the crystal structure, intermolecular C—H⋯O hydrogen bonds link molecules into zigzag chains along c. Additional C—H⋯O interactions connect adjacent chains
