Silver(I) Complexes of Two Flexible Bis‐phospholane Ligands: Metallamacrocycles, Polymeric Chains, and Metallacryptands

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...
