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
