摘要

The YbIII atom in the title complex, [Yb(C27H24Cl3N4O3)] [systematic name: (2,2′,2′′-{(nitrilo)-tris-[ethane-2,1-di-yl(nitrilo)-methylyl-idene]}tris-(4-chloro-phenolato)ytterbium(III)], is coordinated by a trinegative, hepta-dentate ligand and exists within an N4O3 donor set, which defines a capped octa-hedral geometry whereby the amine N atom caps the triangular face defined by the three imine N atoms. The packing features supra-molecular layers that stack along the a axis, sustained by a combination of aryl-C—H?O, imine-C—H?O, methyl-ene-C—H?π(ar-yl) and end-on C—Cl?π(ar-yl) inter-actions. A Hirshfeld surface analysis points to the major contributions of C?H/ H?C and Cl?H/H?Cl inter-actions (along with H?H) to the overall surface but the Cl?H contacts are at distances greater than the sum of their van der Waals radii.
