Water Content-Controlled Formation and Transformation of Concomitant Pseudopolymorph Coordination Polymers.

ABSTRACT: Two concomitant pseudopolymorph coordination polymers {[Cd₂L₂(OAc)₄]·2DMSO} _n (1) and {[CdL(OAc)₂]·2.75H₂O} _n (2) were synthesized by self-assembly of 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene (L) and cadmium acetate in DMSO. Single-crystal X-ray diffraction confirmed that 1D ladder structural motifs exist for pseudopolymorphs 1 and 2 which contain DMSO and water guest molecules, respectively. Our study illustrated the active role of solvent water content in obtaining compound 2. We find that the presence of water as an impurity in the DMSO solvent creates the possibility of formation of concomitant pseudopolymorph coordination polymers which is a unique eve
