In the mol-ecule of the title compound, [InCl(3)(C(12)H(12)N(2))(CH(4)O)], the In(III) atom is six-coordinated in a distorted octa-hedral configuration by two N atoms from the chelating 5,5'-dimethyl-2,2'-bipyridine ligand, one O atom from a methanol molecule and three Cl atoms. In the crystal structure, inter-molecular O-H⋯Cl hydrogen bonds link the mol-ecules into chains parallel to [001].

The title compound, [Ni(2)(C(12)H(12)N(2)O(4)S(3))(H(2)O)(4)]·2C(3)H(7)NO·3H(2)O, is made up of a centrosymmetric, bimetallic complex containing a 24-membered macrocyclic ring, two dimethyl-formamide and three water solvent mol-ecules. The Ni atom adopts a slightly distorted NiO(6) octahedral geometry arising from two O,O-bidentate ligands and two water molecules. There are inter-molecular O-H⋯...

The title compound, C25H33BrN2O4, was synthesized from 9α-hy-droxy-parthenolide (9α-hy-droxy-4,8-dimethyl-12-methylen-3,14-dioxa-tri-cyclo-[9.3.0.0(2,4)]tetra-dec-7-en-13-one), which was isolated from the chloro-form extract of the aerial parts of Anvillea radiata. The mol-ecule is built up from two fused five- and ten-membered rings with an additional ep-oxy ring system and a bromo-phenyl-pipe...

The title compound, C(26)H(36)N(2)O(5), was synthesized from 9α-hy-droxy-parthenolide (9α-hy-droxy-4,8-dimethyl-12-methyl-ene-3,14-dioxatricyclo-[9.3.0.0(2,4)]tetra-dec-7-en-13-one), wich was isolated from the chloro-form extract of the aerial parts of Anvillea radiata. The mol-ecule is built up from fused five- and ten-membered rings with the meth-oxy-phenyl-piperazine group as a substituent. ...
