Abstract: | A mononuclear complex Cu(HL · S)2(NO3)2] ( 1 ) and a one‐ dimensional coordination polymer Cu(HL · S)Cl2]n ( 2 ) HL · S = 4‐(pyridin‐2‐ylmethyl)tetrahydro‐2H‐thiopyran‐4‐ol] showcase the structure‐directing role of the counterions in their formation reaction: monodentate ligation of NO3– and Cl– induces an octahedral (with two HL · S per Cu in 1 ) or trigonal‐bipyramidal (with one HL · S per Cu in 2 ) CuII coordination environment. In contrast to 1 exhibiting no coordinative metal–sulfur bonds in the crystal lattice (space group P21/c), 2 (P21/c) features intermolecular Cu–S contacts of 2.3188(7) Å. The coordination compounds are thermally stable up to ca. 160 °C. Whereas 1 demonstrates the spin‐like behavior of an isolated central CuII ion, compound 2 exhibits weak antiferromagnetic intra‐chain coupling with J ≈ –2.1 cm–1 between neighboring CuII ions. |
