Abstract
The synthesis and structural characterization of ZnLX2 (X = H2O(1), N- 3(-)(2), and NCS-(3); L = ,12-tetramethyl-1,4,8,11-tetraazacyclotetrad ecane) complexes are reported. The crystal structure analysis was empl oyed to determine solid state structures. The crystal structures of th ese complexes have an axially elongated octahedral geometry with two a xial ligands and adopt the trans-III conformation. The long Zn-O bond distance of 2.343(5) Angstrom in complex 1 has a high pK(a) value of 1 1.2. (C) 1998 Elsevier Science Ltd. All rights reserved.
