Diethyl(μ3-2-methyl-4-oxo-4H-pyran-3-olato-κ4 O 3,O 4:O 3:O 3)tris(μ2-2-methyl-4-oxo-4H-pyran-3-olato-κ3 O 3,O 4:O 3)trizinc toluene disolvate
The title compound, [Zn3(C2H5)2(C6H5O3)4]·2C7H8, crystallizes with one complex mol-ecule solvated by two mol-ecules of toluene in the asymmetric unit. The Zn(II) ions are coordinated by two terminal ethyl (Et) groups and four maltolate ligands, which act as μ3- and μ2-bridges. The metal atoms are arranged in an incomplete cubane Zn3O4 core structure, derived from one EtZnO3 tetra-hedron, one Et...
متن کاملsynthesis and cytotoxic activity of some 2-amino-4-aryl-3-cyano-7-(dimethylamino)-4h-chromenes
a series of 2-amino-4-aryl-3-cyano-7-(dimethylamino)-4 h -chromenes was synthesized by condensation of 3-(dimethylamino)phenol, an aromatic aldehyde and malonitrile in ethanol containing piperidine. the assignments of the structure of all synthesized compounds were based on spectral data (ir, mass and 1 h nmr). the cytotoxic activities of the synthesized compounds against six human tumor cell l...
متن کاملcatena-Poly[[diaquacobalt(II)]-μ2-7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylato-κ4 O 2,O 3,O 7:O 2′]
The polymeric title complex, [Co(C(8)H(8)O(5))(H(2)O)(2)](n) was synthesized by reaction of cobalt acetate with 7-oxabicyclo-[2,2,1]heptane-2,3-dicarb-oxy-lic anhydride. The Co(II) ion is six-coordinated in a distorted octa-hedral environment, binding to two water O atoms, to the ether O atom of the bicyclo-heptane unit, to two carboxyl-ate O atoms from two different carboxyl-ate groups of the ...
متن کاملrac-7-Methyl-3-[(7-methyl-4-oxochroman-3-yl)methyl]-4H-chromen-4-one
In the racemic title compound, C21H18O4, the chromone ring is essentially planar [maximum deviation from the least-squares plane = 0.026 (3) Å], with a dihedral angle of 78.18 (12)° between the benzene rings of the chromanone and chromenone moieties. In the crystal, there are weak π-π stacking inter-actions [minimum ring centroid separation = 3.9286 (17) Å].
متن کاملPhase Diagram of weakly pinned YBa 2 Cu 3 O 7 − δ for H ‖ c
Abstract — Vortex phase diagram in a weakly pinned crystal of YBCO for H ‖ c is reviewed in the light of a recent elucidation of the process of ‘inverse melting’ in a Bismuth cuprate system and the imaging of an interface between the ordered and the disordered regions across the peak effect in 2HNbSe2. In the given YBCO crystal, a clear distinction can be made between the second magnetization p...
