which one-dimensional (1D) [Cd2(1,2-BDC)2]n or [Cd2(1,3,5-HBTC)2]n chains are linked by ppene or 4-tp-3-lad bridges. 2 has a three-dimensional (3D) 3-fold interpenetrated framework formed from bridging 1D [Cd2(1,3-BDC)2]n double chains by ppene ligands. Compounds 3a and 5 contain 3D frameworks assembled by linking 2D [Cd2(1,4-BDC)2]n or [Cd2(4,4′-OBA)2]n networks by 4-tp-3-lad or ppene bridges. In the
