A oxovanadium(V) complex of [VOL(C9H6NO)]·CH2Cl2 [H2L=2-hydroxy-1-naphthaldehyde 4-methoxy-benzoylhydrazone, C9H6NO-=8-hydroxyquinoline anion] has been synthesized and characterized by elemental analyses, IR and ...A oxovanadium(V) complex of [VOL(C9H6NO)]·CH2Cl2 [H2L=2-hydroxy-1-naphthaldehyde 4-methoxy-benzoylhydrazone, C9H6NO-=8-hydroxyquinoline anion] has been synthesized and characterized by elemental analyses, IR and single crystal X-ray diffraction. The crystal crystallizes in triclinic system, the space group is P1, with the crystal cell parameters a=1.087 0(2) nm, b=1.107 1(2) nm, c=1.269 3(3) nm, α=67.84(3)°, β=79.26(3)°, γ=73.85(3)° and V=1.353 1(6) nm3, Mr=614.34, R=0.0503, wR=0.1409. The V(V) atom is six-coordinated by one O atom of oxo group, two O atoms and one N atom of the tridentate hydrazone ligand, as well as one N atom and one O atom of 8-hydroxyquinoline ligand, thus defining a distorted octahedral VO(ONO)(NO) geometry. A two-dimensional supramolecular layer structure is formed through π-π stacking interactions. CCDC: 268672.展开更多
The phase diagram of ternary system ErCl_3-CaCl_2-LiCl has been investigated by means of DTA. It was found that there are four fields corresponding to the primary crystallization of ErCl_3,CaCl_2, LiCl and Li_3ErCl_6 ...The phase diagram of ternary system ErCl_3-CaCl_2-LiCl has been investigated by means of DTA. It was found that there are four fields corresponding to the primary crystallization of ErCl_3,CaCl_2, LiCl and Li_3ErCl_6 respectively, five univariant curves related to the secondary crystallization, a ternary eutectic E(58. 5% ErCl_3, 23. 7% CaCl_2, 17. 8%LiCl, 397 ℃) and a ternary peritectic point P(52. 5% ErCl_3, 27. 2% CaCl_2, 20. 3% LiCl, 428 ℃) in the phase diagram. Two ternary reactions occur in the system: L =ErCl_3 + Li_3ErCl_6 +CaCl_2; L+LiCl=Li_3ErCl_6 +CaCl_2.展开更多
