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 title compound, C(19)H(11)NO(3), the isoindolinone ring system is approximately planar with a maximum atomic deviation of 0.071 (1) Å and the five-membered ring of the dihydro-benzo[g]indol-3-one unit assumes an envelope conformation. The naphthalene ring system makes a dihedral angle of 39.47 (4)° with the mean plane of the isoindolinone system. Inter-molecular O-H⋯O and C-H⋯O hydrogen ...
متن کاملSearch for lowest-energy structure of Zintl dianion Si(12)(2-), Ge(12)(2-), and Sn(12)(2-).
We perform an unbiased search for the lowest-energy structures of Zintl dianions (Si(12)(2-), Ge(12)(2-), and Sn(12)(2-)), by using the basin-hopping (BH) global optimization method combined with density functional theory geometric optimization. High-level ab initio calculation at the coupled-cluster level is used to determine relative stabilities and energy ranking among competitive low-lying ...
