title: Photoreactivity of polymorphs of a ladder polymer with criss-cross and parallel orientations of C=C bonds.
abstract: Two polymorphic forms of a ladder coordination polymer [Zn2(μ-O2C-p-Tol)2(O2C-p-Tol)2(bpe)2] have parallel and criss-cross alignments of the C=C bond pairs. Both polymorphs undergo 100% [2+2] cycloaddition reaction but the one with a parallel orientation of C=C bonds (thermodynamic product) retains its single crystallinity after the reaction.
