The structure of [Al2(pydc)2(μ2-OH)2(H2O)2]n(pydc=2,5-pyridinedicarboxylate) was successfully determined from powder X-ray diffraction data. The compound crystallizes in the triclinic system (space group P -1) with a=6.7813(1) A° , b=7.4944(1) A°, c=8.5013(1) A° , α=95.256(1)°, β=102.478(1)°, γ=108.979(1)°. The structure consists of aluminum ions coordinating N and O in distorted octahedra, sharing an edge through two hydroxide ions. These dinuclear complexes are connected by pydc ions, which at one end coordinate by nitrogen and oxygen and only by oxygen at the other end. The pydc orientation is reversed in the neighboring pydc, forming double stranded chains interconnected by the aluminum dinuclear complexes in a ladder-like arrangement along [001].
