A rare metal-organic 3D architecture with a pseudo-primitive cubic topology with double edges constructed from a 12-connected SBU

The hydrothermal assembly of CdCl2 with isophthalatic acid (H(2)ip) and 1,3-bis(4-pyridyl) propane (bpp) yielded a novel 3D coordination polymeric complex, [Cd-4(ip)(4)(bpp)(2)](n) ( 1), which presents an interesting non-interpenetrated pseudo-primitive cubic (pcu) topology with double edges constructed from a 12-connected SBU.
