A divalent cadmium coordination polymer featuring a complex tetranodal 3-D topology and hexadecameric water clusters

The luminescent coordination polymer {[Cd2(dms)2(bpmp)1.5]•8H2O}n (1, dms = 2,2-dimethylsuccinate, bpmp = bis(4-pyridylmethyl)piperazine) exhibits [Cd2(dms)2(bpmp)]n layers partially pillared by other crystallographically distinct bpmp ligands into a complex 3-D 3,4,5-connected tetranodal network. Hydrogen-bonded hexadecameric water molecule clusters lie in incipient channels.
