Interactions in the ternary system K2MoO4-Lu2(MoO4)3-Hf(MoO4)2 have been studied by X-ray powder diffraction and differential thermal analysis. A new triple (potassium lutetium hafnium)
molybdate with the 5: 1: 2 stoichiometry has been found. Single crystals of this molybdate have been grown. Its X-ray diffraction
structure has been refined (an X8 APEX automated diffractometer, MoK
α radiation, 1960 F(hkl), R = 0.0166). The trigonal unit cell has the following parameters: a = 10.6536(1) ?, c = 37.8434(8) ?, V = 3719.75(9) ?, Z = 6, space group R
c. The mixed 3D framework of the structure is built of Mo tetrahedra sharing corners with two independent (Lu,Hf)O6 octahedra. Two sorts of potassium atoms occupy large framework voids.

A new mixed-ligand complex, Zn(4,4′-bipy){(i-PrO)2PS2}2, was synthesized. Single crystals were grown,and the structure of the complex was determined by X-ray diffraction (CAD-4 diffractometer, MoKα radiation, 14807 Fhkl, R =0.0391. The crystals are monoclinic with unit cell dimensions a-17.569(2), b = 26.253(5), c = 27.915(3) Å, ß =100.70(1)°, V = 12652(3) Å3, Z = 16, dvalc = 1.361 g/cm3, space group P21/n. The structure is formed from infinite zigzag polymer chains stretched along the a axis. The coordination polyhedron of the Zn atom is a distorted tetrahedron formed by two S atoms of two monodentate diisopropyldithiophosphate ligands and two N atoms of two bridging bidentate 4,4′-bipy molecules. When heated in vacuum, the compounds ZnL{(i-PrO)2PS2}2 (L) =phen, 2,2′-bipy, 4,4′-bipy are volatile. 相似文献

Heteroligand complexes [Co2(HMTA)(iso-Bu2PS2)4] (I) (μeff = 4.67 μB) and [Cd2(HMTA)(iso-Bu2PS2)4] (II) have been synthesized. Single crystals of compounds I and II have been obtained. The crystals are monoclinic: a = 32.622(2) Å, b = 9.4891(6) Å, c = 21.7570(13) Å, β = 125.774(1)o, V = 5464.3(6) Å,3, Z = 4, ρcalcd = 1.331 g/cm3 for I; a = 34.6092(7) Å, b = 9.5595(2) Å, c = 22.3473(5) Å, β = 127.144(1)o, V = 5893.5(2) Å, Z = 4, ρcalcd = 1.355 g/cm3 for II; space group for both complexes C2/c. Structures I and II are based on discrete binuclear molecules. The coordination polyhedra of the Co and Cd atoms are distorted tetragonal pyramids NS4, with the bases formed by four S atoms of two bidentate chelating ligand iso-Bu2PS 2 ? and the axial vertices occupied by N atoms of bidentate bridging HMTA ligand. The character of interaction of the molecules in structures I and II is considered. 相似文献

The dinuclear gold(III) complex, [Au2(HL)(L)2](ClO4)3(OH) (I) (HL = 1,3-diaminopropane), with two amide bridges has been synthesized for the first time. According to the X-ray diffraction
data, the crystal structure of complex I consists of the complex cations [Au2(HL)(L)2]4+ and anions ClO4− and OH−. The coordination sites AuN4 are insignificantly distorted squares. In the four-membered ring Au2N2, the gold atoms are bound by the bridging nitrogen atoms of the deprotonated primary amine. 相似文献

Paramagnetic Cu(HL)Cl2 · 0.25CHCl3 (I) and Cu(HL)C12 · 0.25CH2C12 (II), where HL is the optically active morpholino oxime obtained from the terpenoid caryophyllene, were synthesized. The crystals
of Cu(HL)Cl2 · CHCl3 (III) were isolated. According to X-ray diffraction data, the crystals of III are composed of acentric mononuclear complex molecules Cu(HL)Cl2 and solvate molecules CHCl3. In the complex molecules, the Cu ion coordinates two N atoms of the bidentate chelating ligand HL and two C1 atoms at the
vertices of a distorted tetrahedron. The translationally identical molecules of the complex combined by H-bonds form chains
along the axis x. 相似文献
