o-hydroxyphenyloxazoline%metal complex%self-assembly%crystal structure
The chiral o-hydroxyphenyloxazoline ligands were synthesized and their metal complexes with Cu, Ni and Ti were prepared. The crystal structure of complex 2a formed by ligand 1a with Cu (molar ratio 2:1) was determined by single-crystal X-ray diffraction analysis, and it belongs to monoclinic, space group P21 with a = 11.679(2), b = 17.681(4), c = 12.838(3) A, β =106.50(3)°, C26H32N2O4Cu, Mr = 500.08, V = 2541.8(9) A3, Z = 4, F(000) = 1052, Dc = 1.307 g/crm3,μ = 0.892 mm-1, the final R = 0.0448 and wR = 0.0930 (Ⅰ＞ 2σ(Ⅰ)). In the asymmetric unit of interactions, and "dimeric complex" is thus formed. The distancesof the Cu and O atoms of a pair O(13), respectively. The coordination N and O atoms and the central Cu are slightly deviated from coplanarity.
