Abstract
In a 2:2 reaction with silver(I) chloride or bromide, 1,5-bis(1-phospholano)pentane (1a) afforded frame-like macrocyclic structures, with intra- (2, Cl) or intermolecular (3, Br) halido bridges. In contrast, 1,7-bis(1-phospholano)heptane (1b) formed coordination polymers 4a (Cl) and 4b (Br) with bridging bis-phospholane and halido ligands. A unique paddle wheel-type metallacryptand structure 5 was obtained from 1a and silver(I) bromide in a 2:3 reaction (M:L). All complexes were fully characterized by NMR, IR spectroscopy, mass spectrometry, and X-ray crystallography.
期刊介绍：
ZAAC is an international scientific journal which publishes original papers on new relevant research results from all areas of inorganic chemistry, solid state chemistry, and co-ordination chemistry.
The contributions reflect the latest findings in these research areas and serve the development of new materials, such as super-hard materials, electrical superconductors, or intermetallic compounds. Up-to-date physical methods for the characterization of new chemical compounds and materials are also described.
