Inertial measurement units (IMUs) are mobile sensors assemblies constructed using a combination of MEMS (micro electrical mechanical systems) accelerometers, gyroscopes and magnetometers. Both the technology its applications to geomorphic problems developing rapidly, since they demonstrate prospect monitoring individual sediment grains, various sizes, during transport at high frequency. This ha...

The mol-ecule of the title compound, C(12)H(16)Cl(2)O(2), has a center of inversion at the centroid of the benzene ring and the asymmetric unit contains one half-mol-ecule. Inter-molecular C-H⋯π inter-actions stabilize the crystal structure.

In the title compound, [Tb(C(7)H(4)NO(4))(3)]·2.75H(2)O, the Tb(3+) atom is coordinated by three tridentate 6-carb-oxy-pyridine-2-carboxyl-ate ligands and lies on a crystallographic threefold rotation axis. The coordination polyhedron around Tb(III) adopts a distorted tricapped trigonal-prismatic geometry. Disordered water mol-ecules with partial occupancy are also present in the crystal, one o...

The mol-ecular skeleton of the title mol-ecule, C(9)H(11)NOS, is essentially planar: the thio-phene ring is inclined to the mean plane of the rest non-H atoms by 2.92 (3)°. The crystal packing exhibits no significantly short inter-molecular contacts.

The title mol-ecule, C(16)H(24)N(2)OS, is twisted about the central N(H)-C bond with a C-N(H)-C-N torsion angle of -62.67 (15)°. The carbonyl group is twisted out of the plane of the benzene ring, forming a C-C-C=O torsion angle of -25.06 (17)°. In the crystal, mol-ecules related by centres of symmetry are linked by pairs of inter-molecular N-H⋯S hydrogen bonds, forming eight-membered {⋯HNCS}(2...
