| Abstract: Two new chiral oxovanadium complexes,[VO(Naph-Leu)(OMe)(CH3OH)] (1) and[VO(Naph-Phe)(OMe)(CH3OH)] (2), (Naph-Leu=Schiff base derived from 2-hydroxy-1-naphthaldehyde and L-leucine, Naph-Phe=Schiff base derived from 2-hydroxy-1-naphthaldehyde and L-phenylalanine), have been synthesized. Single crystal X-ray diffraction analysis showed that complex 1 crystallized in the orthorhombic crystal system, space group P21212 with the cell parameters: a=0.946 80(8) nm, b=3.246 3(3) nm, c=0.662 37(5) nm, V=2.035 9(3) nm3, Z=4, F(000)=864, R1=0.046 3, wR2=0.112 7, S=1.076; and complex 2, crystallized in the monoclinic crystal system, space group P21 with the cell parameters: a=1.113 41(11) nm, b=0.724 09(6) nm, c=1.342 99(12) nm, V=1.047 95(16) nm3, Z=2, F(000)=464, R1=0.035 8, wR2=0.088 8, S=1.024. The IR, UV-Vis and circular dichroism (CD) spectra of the two complexes were measured and discussed. CCDC: 885240, 1; 897188, 2. | |
