A porous coordination polymer of Sn-Cu xylarate [Sn{sub 4}Cu{sub 8.5}(HL){sub 2}(L){sub 4}O{sub 2}(OH)(H{sub 2}O){sub 12.5}] {center_dot} 17.2H{sub 2}O (H{sub 5}L is xylaric acid) is synthesized for the first time and characterized by chemical analysis, IR spectroscopy, and X-ray diffraction. Centrosymmetric heterometallic fragments [Sn{sub 4}Cu{sub 6}(HL){sub 2}(L){sub 4}O{sub 2}(H{sub 2}O){sub 6}] (A) including copper Cu1-3 and tin Sn1,2 atoms are distinguished in the structure. The Cu4(OH){sub 0.5}(H{sub 2}O){sub 2.5} bridges connect A units into chains running along the c axis, and the Cu5(OH)(H{sub 2}O) bridges connect A fragments into layers perpendicular to the c axis. The Cu4,5 atoms form a framework whose voids accommodate the crystallization water molecules.
