Crystals of cis-bis(4-ethylthiosemicarbazide)nickel(II) terephthalate (I) are monoclinic, space group C2/c, with a 12.102(6), b 15.053(7), c 12.451(11).ANG., beta 118.80(3) Deg; Z = 4; R = 0.0430, Rw2 = 0.1353 for 1754 reflections. The cations and anions are linked into H-bonded chains via interactions between two H bond donors on the thiosemicarbazide ligands and two H bond acceptors on the terephthalate (DD:AA). In contrast to the structures of trans-bis(thiosemicarbazide)nickel(II) dicarboxylates, the DD motifs are derived from the amino NH bonds, and are comprised of one H bond donor from each ligand on the complex. Consequently, the supramol. structure of I is different to those obsd. for trans-bis(thiosemicarbazide)nickel(II) dicarboxylates, and the cations and anions lie almost perpendicular to each other in the crystal structure.
