[Bis-picrate(pentaethylene glycol)]praseodymium(III) picrate, [Pr(pic)2⋅(EO5]+[pic]−, was successfully obtained from the reaction of praseodymium nitrate hexahydrate, picric acid and pentaethylene glycol in acetonitrile–methanol as solvent. The crystal system is monoclinic with space group P21/c, a = 18.91419(11) Å, b = 9.0470(6) Å, c = 24.1209(14) Å and α = γ = 90∘, β = 109.07(1)∘, V = 3880.3(4) Å3 and Z = 4. The Pr atom is coordinated to the flexible and open EO5 ring via all the six oxygen atoms and two picrate ligands, one via phenoxo oxygen atom and the other one with both phenoxo and nitro oxygen atoms in a bidentate manner resulting a 9-coordinate tricapped trigonal prismatic geometry. The two picrate ligands coordinated to the Pr atom are at the opposite sides of the hexadentate EO5 ring with phenyl fragments almost perpendicular with dihedral angle of 89.7(3)∘. Thermal analysis results show that the complex is stable up to 100∘C when it began to slowly decompose and followed by an explosive decomposition at 290∘C. 相似文献

Momentum map is a reduction procedure that reduces the dimension of a Hamiltonian system to the lower ones. It is shown that
behavior of the action-angle variables under the momentum map generates the new action-angle variables for the reduced system
considered as a Nambu structure. The symmetrical top is given as an illustration.

The title compound was formed upon slow evaporation of a solution of the solvated dicationic complex bis(acetonitrile)bis[1,2‐bis(diphenyl‐phosphino)ethane]palladium(II) bis(tetrafluoroborate) in deuterated chloroform. The dinucleur palladium complex forms triclinic crystals and there is an inversion center between the Pd atoms. Compared to the corresponding monomeric compound, the Cl—Pd—Cl angles decrease upon briding from 94.19 (7) to 86.96 (4)°. 相似文献
