2,3-Dimeth-oxy-5,12-tetra-cenequinone.

ABSTRACT: The mol-ecule of the title compound, C(20)H(14)O(4), is approximately planar [maximum deviation 0.168?(2)?Å]. The two meth-oxy groups are slightly twisted relative to the plane of the 5,12-tetra-cenequinone system, with twist angles of 3.3?(3) and 5.6?(2)°. All O atoms are involved in intermolecular C-H?O inter-actions and the mol-ecules are arranged into slipped face-to-face stacks along the b axis via ?-? inter-actions with an inter-planar distance of 3.407?(2)?Å.

The mol-ecule of the title compound, C(20)H(14)O(4), is approximately planar [maximum deviation 0.168 (2) Å]. The two meth-oxy groups are slightly twisted relative to the plane of the 5,12-tetra-cenequinone system, with twist angles of 3.3 (3) and 5.6 (2)°. All O atoms are involved in intermolecular C-H⋯O inter-actions and the mol-ecules are arranged into slipped face-to-face stacks along the b axis via π-π inter-actions with an inter-planar distance of 3.407 (2) Å. ...[more]

Tetra-kis(?-3,4-dimeth-oxy-phenyl-acetato)-bis-[(3,4-dimeth-oxy-phenyl-acetato)(1,10-phenanthroline)holmium(III)].

Project description:In the centrosymmetric title compound, [Ho(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the Ho(III) atom is nine-coordinated by seven O atoms from the 3,4-dimeth-oxy-phenyl-acetate (L) anions and two N atoms from a 1,10-phenanthroline (phen) mol-ecule. The L ligands are coordinated to the Ho(III) ions in three modes: chelating, bridging and bridging-tridentate. Intra-molecular C-H?O inter-actions occur. The crystal packing is stabilized by inter-molecular C-H?O inter-actions and weak aromatic ?-? inter-actions between phen mol-ecules and the aromatic rings of the L ligands [centroid-centroid distance = 3.821?(2)?Å].

Bis(2,3-dimeth-oxy-10-oxostrychni-din-ium) phthalate nonahydrate.

Project description:The asymmetric unit of the title compound 2C23H27N2O4 (+)·C8H4O4 (2-)·9H2O, contains a cation, an anionon a twofold axis and four and half mol-ecules of water, one of which is located on the twofold axis. In the cation, both fused pyrrolidine rings exhibit twisted conformations, while the piperidine rings adopt screw-boat and boat conformations. In the crystal, the components are linked by N-H?O and O-H?O hydrogen bonds. The brucinium cations form typical undulating head-to-tail ribbon structuresalong the a-axis direction, which associate with the carb-oxy phthalate and the water mol-ecules.
