Unusual parallel and inclined interlocking modes in polyrotaxane-like metal–organic frameworks†
Abstract
We describe here two unusual polyrotaxane-like metal–organic frameworks of [Co2(1,3-bix)2(bpea)2] 1 and [Cd4(1,4-bix)4(bpea)4]·4H2O 2, where both species contain loops and rods that are interlaced in a highly rare “parallel” fashion in 1, but, uniquely, in an “inclined” fashion in 2.
