Crystal structure of a layered coordination polymer based on a 44 net containing Cd2+ ions and 1,5-bis(pyridin-4-yl)pentane linkers

Abstract

The title compound, poly[[diaquabis[1,5-bis(pyridin-4-yl)pentane-κ2N:N′]cadmium] bis(perchlorate) 1,5-bis(pyridin-4-yl)pentane ethanol monosolvate], [Cd(C15H18N2)2(H2O)2](ClO4)2·C15H18N2·C2H6O, is a layered coordination polymer built up from highly squashed 44 nets in which the octahedral trans-CdO2N4 nodes (Cd site symmetry -1) are linked by the bifunctional ligands, forming infinite (110) sheets. The cationic sheets are charge-balanced by interlayer perchlorate ions. A free 1,5-bis(pyridin-4-yl)pentane molecule and an ethanol molecule of crystallization are also found in the intersheet region. A number of O—H...O, O—H...N and C—H...O hydrogen bonds help to consolidate the layered structure.
