In the title compound, C10H14Cl3NO5, the five-membered dioxolane ring adopts an envelope conformation. The C atom at the flap, which is bonded to the hy-droxy-methyl substituent, deviates from the mean plane of other ring atoms by 0.357 (5) Å. There are two intra-molecular hydrogen bonds (O-H⋯N and N-H⋯O) between the hy-droxy and amino groups, so that O- and N-bound H atoms involved in these hy...

In the title complex, [CoCl(2)(C(12)H(8)N(2))(2)]·C(3)H(7)NO, which has twofold rotation symmetry, the Co(II) cation is coordinated by two 1,10-phenanthroline (phen) mol-ecules and two chloride ligands in a distorted octa-hedral geometry. In the crystal structure, a cavity is created by six complex mol-ecules connected by C-H⋯π inter-actions and non-classical C-H⋯Cl hydrogen bonds. The cavities...

In the title compound, [Co(C(7)H(7)N(2)O(4))(2)(H(2)O)(2)]·3H(2)O, the Co(II) cation, located on an inversion center, is N,O-chelated by two 5-carboxy-2-ethyl-1H-imidazole-4-carboxylate anions and further coordinated by two water mol-ecules in a distorted octa-hedral geometry. Only one carboxy group of the anion is deprotonated, and the two carboxyl groups of the same anion are linked via an in...

Hexalithium calcium disamarium(III) ditantalum(V) dodeca-oxide, Li(6)CaSm(2)Ta(2)O(12), crystallizes in a cubic garnet-type structure. In the crystal structure, disordered Li atoms occupy two crystallographic sites. One Li has a tetra-hedral coordination environment in the oxide lattice, whereas the other Li atom occupies a significantly distorted octa-hedral site, with site occupancies for the...

The title compound, [Cu(2)(CN)(SCN)(C(10)H(8)N(2))(2)](n), contains two crystallographically independent Cu(I) atoms, each in a distorted tetra-hedral geometry. Each Cu atom is coordinated by a bidentate chelating 2,2'-bipyridine ligand. A bridging cyanide anion links the two Cu(2,2'-bipyridine) units to form a binuclear unit. Adjacent binuclear units are connected by a thio-cyanate anion into ...

In the title indole derivative, C16H10BrCl2NO, the dihedral angle between the mean plane of the indole ring system and the mean plane of the disordered 2-bromo-phenyl ring is 77.6 (1)°. The non-H atoms of the chloracetyl group are essentially coplanar with the indole core. In the crystal, pairs of mol-ecules are face-to-face embraced via two weak C-H⋯O hydrogen bonds, forming inversion dimers w...

The title compound, tert-butyl-propoxycalix[5]arene, C(70)H(100)O(5)·0.5CH(2)Cl(2), crystallizes as a solvate with two mol-ecules of calix[5]arene in 1,2-alternate conformations and one mol-ecule of dichloro-methane in the asymmetric unit. One tert-butyl group in one of the mol-ecules and two in the other are disordered over two positions with occupancy factors fixed at 0.5917:0.4083, 0.5901:0....

Sm2Fe17 compounds are high-performance permanent magnets. Cobalt substitution allows us to further improve their magnetic properties. Depending on the thermal treatment, cobalt-substituted can be synthesized either in TbCu7 (disordered) or Th2Zn17 (ordered) structure type. Rietveld refinement of number transition metal dumbbells replacing rare-earth atoms from synchrotron powder diffraction dat...

introduction: there is a long-term interest in the effects of undesirable emotions to eating behaviors, due to the strain that it places on a person which can lead to loses his/her health. the present study examined the degree of disordered eating behaviors related to anxiety and alexithymia among high schools girls.materials and methods: this cross-sectional study on 344 girl students of tehra...

In the title complex, [Cu(2)(CN)(2)(C(6)H(7)N)](n), there are two copper atoms with different coordination environments. One Cu atom (Cu1) is linked to the two cyanide ligands, one N atom from a pyridine ring while the other (Cu2) is coordinated by the two cyanide ligands in a slightly distorted tetra-hedral geometry and linked to Cu1, forming a triangular coordination environment. The Cu atoms...
