Optical and nonlinear laser properties of the χ(3)-active monoclinic α-KY(WO4)2 crystals

Monoclinic α-KRE(WO4)2 crystals are grown. Their structure is described in two crystallographic settings. The principal refractive indices are determined and the coefficients and characteristic wavelengths are used for calculating refractive indices by the Selmeyer formulas. The data on the anisotropic parametric Raman generation in these crystals under the picosecond pumping are discussed.

Synthesis and crystal and molecular structure of mixed-ligand compounds Eu(S2CN(C2H5)2)3(2,2′-Bipy) and Eu(S2CN(C2H5)2)3(1,10-Phen)

Synthetic procedures were developed and X-ray diffraction analysis was performed for two mixed-ligand compounds of europium(III) with diethyldithiocarbamate ions and 2,2′-bipyridyl (2,2′-Bipy) or 1,10-phenanthroline (Phen): Eu(S2CN(C2H5)2)3(2,2′-Bipy) (I) and Eu(S2CN(C2H5)2)3Phen (II). The structures of the complexes consist of discrete monomer molecules; the coordination polyhedron of Eu (EuN2S6 is a node) is a distorted dodecahedron.

Phase formation in the Rb2MoO4-Er2(MoO4)3-Hf(MoO4)2 system and the crystal structure of new triple molybdate Rb5ErHf(MoO4)6

AbstractThe subsolidus region of the Rb2MoO4-Er2(MoO4)3-Hf(MoO4)2 ternary salt system is studied using X-ray powder diffraction. A novel 5: 1: 2 triple molybdate, Rb5ErHf(MoO4)6, is found to form in the system. Crystals of Rb5ErHf(MoO4)6 are flux-grown under spontaneous nucleation conditions. The composition and crystal structure of Rb5ErHf(MoO4)6 are refined in a single-crystal X-ray diffraction experiment (X8 APEX diffractometer, MoKα radiation, 1753 reflections, R = 0.0183). The crystals are trigonal; a = 10.7511(1) Å, c = 38.6543(7) Å, V = 3869.31(9) Å3, dcalc = 4.462 g/cm3, Z = 6, space group % MathType!MTEF!2!1!+-% feaafiart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn% hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr% 4rNCHbGeaGqiVu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq-Jc9% vqaqpepm0xbba9pwe9Q8fs0-yqaqpepae9pg0FirpepeKkFr0xfr-x% fr-xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaamOuaiqaio% dagaqeaiaadogaaaa!3881!

Co(III) complexes with optically active bis(menthane), pinano-para-menthane, carano-para-menthane, and bis(carane) propylenediaminodioximes

. The mixed three-dimensional framework of the structure is formed of MoO4 tetrahedra, each sharing corners with two ErO6 and HfO6 octahedra. Two types of Rb atoms occupy large cavities of the framework. The distribution of the Er3+ and Hf4+ cation over two positions is refined in the course of structure solution.

Synthesis and photoluminescence of the chiral compounds [ZnLCl2] · EtOH and ZnLCl2, where L is the (+)-3-Carene derivative containing pyrazoline and quinoline fragments: crystal structure of [ZnLCl2] · EtOH

AbstractBinary molybdates K4M2+ (MoO4)3 (M2+=Mg, Mn, Co) isostructural to triclinic \ga-K4Zn(WO4)3 were synthesized, and optimal conditions for their spontaneous crystallization were found. It was established by XRPA and DTA that at 530°C the structure of the compound with cobalt undergoes a transition to the orthorhombic structure of K4Zn(MoO4)3. The structure of K4Mn(MoO4)3 was determined from single crystal diffraction data (a=7.613, b=9.955, c=10.156 Å,α=92.28,β=106.66,γ=105.58°, Z=2, space group
