The crystal crystallizes in orthorhombic system, space group P bca with a =1 503 2(3), b =1 819 5(4), c =2 330 2(5) nm, V =6 373(2) nm, Z =8, D c = 1 348 g/cm 3 , μ =0 971 mm -1 (Mo Kα ), F (000)=2 720. The structure was refined to R =0 048 9 and wR = 0 094 3 for observed 2 978 reflections with I≥2σ(I) . The Zn(Ⅱ) ion has a distorted tetrahedral coordination consisting of two chlorine ions and the two oxygen atoms from two Schiff base ligands.展开更多
The new solid complexes [LnL2(NO3)2]NO3 (L=C18H23NO2, N-2-hydroxy-3-me thoxy-benzaldehyde-1-aminoadamanantane, Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, H o, Er, Tm, Yb, Lu, Y) of rare earth nitrates with Schiff base der...The new solid complexes [LnL2(NO3)2]NO3 (L=C18H23NO2, N-2-hydroxy-3-me thoxy-benzaldehyde-1-aminoadamanantane, Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, H o, Er, Tm, Yb, Lu, Y) of rare earth nitrates with Schiff base derived from o-van illin and adamantaneamine have been synthesized in non-aqueous system and charac terized by elemental analysis, molar conductance, infrared spectra, 1H NMR spect ra, thermal analysis. The coordination modes of the bonding in these complexes w ere discussed and the possible structure were proposed. Every central Ln(III) io n in the complexes coordinates with both two Schiff base ligands via four oxygen atoms of the phenol hydroxy groups and methoxy groups and two nitrates via thei r four oxygen atoms. Their coordination numbers are eight. In addition, the anti bacterial activity of the Schiff base ligand and the complexes were studied.展开更多
