12-Benzoyl-2-methyl­naphtho­[2,3-b]indolizine-6,11-dione

In the title compound, C(24)H(15)NO(3), the fused naphthaquin-one-pyrrole unit is approximately planar, the naphthaquinone ring system making a dihedral angle of 2.91 (10)° with the pyrrole ring. The plane of the pyrrole ring makes a dihedral angle 61.64 (14)° with that of the benzene ring of the benzoyl-methyl-ene group. The crystal structure is stablized by intra-molecular C-H⋯O inter-actions.

In the asymmetric unit of the title organic-inorganic hybrid material, 2{H(3)[PW(12)O(40)]}·4C(3)H(4)N(2)O(2)·C(7)H(8)N(4)O(4)·21.5H(2)O, there are four crystallographically independent hydantoin mol-ecules, one dimerized hydantoin mol-ecule, viz. 1,1'-methyl-enebis(imidazolidine-2,4-dione, two independent H(3)PW(12)O(40) mol-ecules and 21.5 solvent water mol-ecules. Nine of the solvent water m...

E 12 Million Salaried Workers Are Missing

Evidence from Current Population Surveys, various cohorts of the National Longitudinal Surveys, and the Panel Study of Income Dynamics suggests that the fraction of American employees who were paid salaries held constant from the late 1960s through the late 1970s, and continued to hold constant or perhaps fell slightly thereafter through the late 1990s. An analysis that accounts for the changin...

16-[(E)-Benzyl­idene]-13-hy­droxy-4-methyl-2-phenyl-4,14-diaza­penta­cyclo-[12.3.1.01,5.05,13.07,12]octa­deca-7(12),8,10-triene-6,17-dione

In the title compound, C(30)H(26)N(2)O(3), the two pyrrolidine rings adopt twisted and envelope conformations, whereas the cyclo-pentane ring adopts an envelope conformation. The least-squares planes through the pyrrolidine rings form a dihedral angle of 41.72 (10)°. The mol-ecular structure is stabilized by an intra-molecular O-H⋯N hydrogen bond, which generates an S(5) ring motif. Centrosymme...
