title: Coordination polymers based on square planar Co(II) node and linear spacer: solvent-dependent pseudo-polymorphism and an unprecedented interpenetrating structure containing both 2D and 3D topological isomers.
abstract: Reaction of Co(NCS)2 with 1-methyl-1'-(4-pyridyl)-2-(4-pyrimidyl)ethylene (mppe) in different solvents yields two kinds of novel coordination polymer structures of [Co(mppe)2(NCS)2]n: one of them shows an unprecedented interpenetrating structure with both 2D and 3D topological isomers.
