Popis:	To investigate the influences of ligand spacers of flexible bis(thioether) bridging ligands on the framework formations of their complexes, six new AgI coordination compounds with a series of structurally related bis(tert-butylthio)alkane ligands, Ln = (CH3)3CS-(CH2)n-SC(CH3)3 where n = 1−6, [(AgL1)ClO4]n (1), {[Ag(L2)1.5]ClO4}n (2), [(AgL3)ClO4]2 (3), {[Ag(L4)1.5]ClO4}n (4), [(AgL5)ClO4]2 (5), and {[Ag(L6)1.5]ClO4}n (6), have been synthesized and structurally characterized by elemental analysis, IR, 1H NMR spectra, and X-ray crystallography. In 1, the AgI centers are linked by bridging L1 to form a one-dimensional (1-D) zigzag chain, and complex 2 has an extended two-dimensional (2-D) (6,3) topologic array with hexagonal 30-membered macrometallacycles. Complexes 3 and 5 show similar discrete dinuclear structures. Complexes 4 and 6 consist of single-double bridging chains in which dinuclear macrometallacycles are further linked by single bridging L ligands. The differences among these structures indicate ...
