Single crystals of triple molybdate of composition 5:1:3 K5Pb0.5Hf1.5(MoO4)6 have been grown and their crystal structure has been solved from X-ray diffraction data (an automated diffractometer X8 APEX, MoK α -radiation, 2173 F(hkl), R = 0.0321). Trigonal unit cell parameters are: a = b = 10.739(2) Å, c = 37.933(9) Å; V = 3789(1) Å3, Z = 6, ρcalc = 4.014 g/cm3, space group \(R\bar 3\). Three-dimensional mixed framework of the structure is formed by two types of MoO4 tetrahedra and Pb and Hf octahedra linking via common O-vertices. Potassium atoms of three types occupy large vacancies in the framework. 相似文献

Methyl 3-[(3,5-dimethylpyrazole-1-carbothioyl)-amino]propionate (L1) and the optically active derivative of natural monoterpene (+)-3-carene, (3bS,4aR)-3-[(3,4,4-trimethyl-3b,4,4a,5-tetrahydro-cyclopropa[3,4]cyclopenta[1,2-c]pyrazole-1-carbothioyl)-amino]propionate (L2), are synthesized. The paramagnetic CuL1Cl2 (I) and [Cu2L2
2Cl4] (II) complexes are obtained. According to the X-ray diffraction data, in mononuclear complex I, the L1 molecule performs a bidentate-cyclic function due to the coordination of the S atom of the C=S group and the N atom of the pyrazole cycle. The CuCl2NS coordination polyhedron is a distorted tetrahedron. Two molecules of complex I form an associate due to weak Cu···S interactions. Compound II is binuclear due to the bridging function of two Cl- ions, and analogous functions of the L1 and L2 ligands. The coordination polyhedron in complex II is CuCl3NS. The eff values for compounds I and II are equal to 1.81 and 1.79 B, respectively, and are constant in the interval from 78 to 300 K, indicating that noticeable exchange interactions between unpaired electrons of the Cu2+ ions are absent. The EPR spectra of the complexes in the solid phase are examined. 相似文献

Single crystals of CsNaMoO4 · 2H2O were synthesized, and the crystal structure of this compound was determined from X- ray diffraction data (SYNTEX P21 automatic diffractometer, MoKα radiation, 2252 reflections, R =0.037). Crystals are orthorhombic, space group P212121 with unit cell dimensions a =6.379(1), b =8.625(1), c =13.671(2) å, Z =4. The structure of the binary molybdate consists of continuous columns of face- sharing Na octahedra with attached MoO4 tetrahedra. The neighboring columns are linked by the Cs cations and the hydrogen bonds of the water molecules entering into the coordination polyhedra of the Na and Cs atoms. 相似文献

Systems Tl2MoO4-E(MoO4)2 (E = Zr, Hf) are studied using X-ray powder diffraction, DTA, and IR spectroscopy. Compounds Tl8E(MoO4)6 and Tl2E(MoO4)2 are found in these systems. T-x diagrams for the Tl2MoO4-Zr(MoO4)2 system are designed. Single crystals are grown and structure is solved for Tl8Hf(MoO4)6. The compound crystallizes in a monoclinic structure with the unit cell parameters a = 9.9688(6) Å, b = 18.830(1) Å, c = 7.8488(5) Å, β = 108.538(1)°, Z = 2, space group C2/m. The main structural fragment is a [HfMo6O24]8? isle group. Three crystallographically independent types of Tl polyhedra uniformly fill spaces between [HfMo6O24]8? fragments to form a three-dimensional framework. 相似文献

Based on structural data, the interaction between the coordinated Phen molecules of complexes I, [Ni(Phen)2(iBu2PS2)](iBu2PS2) (II), and III is considered, as well as the packing modes of these complexes. 相似文献
