In the crystals of trans-bis(pyridine-N)bis(2-thiopheneglyoxylato-O1,O 2)copper(II), [Cu(C6H3O3S)2(C5H 5N)2], there is a mononuclear CuII complex molecule. In the crystal of catena-poly[[[bis(2-thiopheneglyoxylato-O1,O 2)copper(II)]-μ-(2-thiopheneglyoxylato-O1:O 1′,O 2)-[bis(3-methylpyridine-N)copper(II)]-μ-(2-thiopheneglyoxylato- O1,O2:O1′)] monohydrate], {[Cu2(C6H3O3S)4-(C 6H7N)2]·H2O}n, there is a zigzag polymer chain where the CuII atoms are bridged by the thiopheneglyoxylate ions. In the crystal of cis-bis(4-methylpyridine-N)bis(2-thiopheneglyoxylato-O1,O 2)copper(II), [Cu-(C6H3O3S)2(C6H 7N)2], there is a mononuclear CuII complex. The coordination geometry around the Cu atoms is distorted octahedral. Each thiopheneglyoxylate ion adopts a flattened structure and forms a five-membered chelate ring with the Cu atom.
