The asymmetric unit of the title compound, [Fe(C(8)H(7)N(3))(3)](2)[SiMo(14)O(44)], consists of a complex [Fe(C(8)H(7)N(3))(3)](2+) cation and half of a derivative of an α-Keggin-type anion, [SiMo(14)O(44)](4-). In the mixed-valent Mo(V/VI) anion, the α-Keggin type core is capped on two oppositely disposed tetra-gonal faces by additional (MoO(2)) units. The [SiMo(14)O(44)](4-) anion shows disor...
In the title dinuclear Cu(II)-Lu(III) salen-type complex, [CuLu(C(22)H(24)N(2)O(4))(NO(3))(3)], with the ligand 6,6'-dimeth-oxy-2,2'-[cyclo-hexane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate, the irregular nine-coordinate Lu(III) coordination sphere comprises four O atoms from the ligand and five O atoms from three nitrate groups, two bidentate and one monodentate [Lu-O = 2.230 (3)-2.621 (4) ...
In the title complex, [Ni(C17H16N2O5)]·2H2O, the Ni(II) ion is four-coordinated by two azomethine N and two phenolato O atoms of the tetradentate Schiff base ligand in a slightly distorted square-planar geometry. In the six-membered ring containing the metal, the azomethine N atoms and the three C atoms of the connecting 1,3-di-amino-propane-2-ol, all atoms except the metal are disordered over ...
The dinuclear title complex, [Cu(2)(C(46)H(38)N(4)O(2))Cl(2)]·0.5C(2)H(5)OH·2H(2)O, is located on crystallographic inversion centres with two half-mol-ecules in the asymmetric unit. The two Cu(II) atoms are coordinated by a hexa-dentate dianionic ligand formed in situ from the condensation of two tridentate ligands by four imine N atoms and two bridging phenolate O atoms along with two Cl atoms...
In the title compound, [Ni(C(15)H(13)FNO(2))(2)], the Ni(II) atom is tetra-coordinated by two N atoms and two O atoms from two 2-[(4-fluoro-benz-yl)imino-meth-yl]-6-meth-oxy-phenolate ligands in a square-planar geometry. The two N atoms and two O atoms around the Ni(II) atom are trans to each other, as the Ni(II) atom lies on an inversion centre. In the fluoro-phenyl group, five C atoms and an ...
background: this study aimed to highlight the proportion of disordered eating attitudes among university students in kuwait by gender and obesity. methods: a sample of 530 kuwaiti university students was selected from four universities in kuwait (203 men and 327 women). the eating attitudes test‑26 was used to determine disordered eating attitudes. results: the prevalence of disordered eating a...
The title compound, C(42)H(36)N(4)O(5)·0.25CH(3)CN, crystallizes with a partial twofold disordered (1/4) acetonitrile solvent of crystallization. The linking atoms to the 3,5-bis-(benz-yloxy)benzoic acid are disordered between two conformations in the ratio 0.780 (6):0.220 (6). In the crystal, the mol-ecules pack using mainly C-H⋯N(cyano) inter-actions coupled with weak C-H⋯O(ether) inter-actio...
In the title compound, C(26)H(32)N(8)O(6) (2+)·2BF(4) (-), the cation is built up from four fused rings, viz. two nearly planar imidazole rings and two triazine rings exhibiting chair conformations. One eth-oxy group is disordered between two positions in an approximate ratio 3:2. The F atoms of the two anions are each rotationally disordered between two orientations in the same 3:2 ratio. The ...
