(E)-3-Hydr­oxy-13-methyl-16-[4-(methyl­sulfan­yl)benzyl­idene]-7,8,9,11,12,13,15,16-octa­hydro-6H-cyclo­penta­[a]phen­an­­­­thren-17(14H)-one

In the title compound, C(26)H(28)O(2)S, the dihedral angles between the mean plane of the five membered ring and the 4-(methyl-sulfan-yl)benzyl-idine ring in the two crystallographically independent mol-ecules are 34.05 (10) and 40.53 (15)°. The packing is stabilized by inter-molecular O-H⋯O and C-H⋯O inter-actions.

(1′S,12′R,13′S,17′S)-15′,15′-Dimethyl-1,2-dihydro-11′,14′,16′,18′-tetra­oxa-7′-aza­spiro­[indole-3,8′-penta­cyclo­[10.6.0.02,9.03,7.013,17]octa­deca­ne]-2,10′-dione

In the title compound, C22H24N2O6, the indole ring has a twist conformation and the tetra-hydro-2H-pyran-2-one ring a half-chair conformation. One of the pyrrolidine rings adopts an envelope conformation on the N atom, while the other has a twist conformation; the 'butterfly' angle between their mean planes is 62.98 (11)°. The dioxolane ring adopts a twist conformation and the tetra-hydro-furan...

Nickel and cobalt complexes of 15 , 15 - disubstituted 1 , 4 , 7 , 10 , 13 - pentaazacyclohexadecane - 14 , 16 - dione ligands

The synthesis of the novel Co(III)(15,15-difluoro-1,4,7,10,13-pentaazacyclohexadecane-14,16dione) acetate complex from different cobalt sources is described. Furthermore, the corresponding nickel complex and its new analog with the 15-fluoro-15-methyl-1,4,7,10,13-pentaazacyclohexadecane-14,16dione ligand were studied in great detail including cyclic voltammetry and single crystal analyses of a ...
