Abstract	Two isomeric NS$_{2}$-macrocycles incorporating a xylyl group at ortho (o -L) and meta (m -L) positions were employed and their copper complexes (1–5) were prepared and structurally characterized. The copper(II) nitrate complexes [Cu(L)(NO$_{3}$)$_{2}$] (1: L = o -L, 2: L = m -L) for both ligands were isolated. In each case, the copper center is five-coordinated with a distorted square pyramidal geometry. Despite the overall geometrical similarity, 1 and 2 show the different ligand conformation due to the discriminated packing pattern. Reaction of o -L with copper(II) perchlorate afforded complex 3 containing two independent complex cations [Cu(o -L)(H$_{2}$O)(DMF)(ClO$_{4}$)]$^{+}$ and [Cu(o -L)(H$_{2}$O)(DMF)]$^{2+}$; the coordination geometry of the former is a distorted octahedron while the latter shows a distorted square pyramidal arrangement. In the reactions of copper(I) halides (I or Br), o -L gave a mononuclear complex [Cu(o-L)I] (4) with a distorted tetrahedral geometry, while m -L afforded a unique exodentate 2:1 (ligand-to-metal) complex [trans-Br$_{2}$Cu(m-L)$_{2}$] (5) adopting a trans-type square-planar arrangement.
