A novel coordination polymer [Ba-2(AQTC)(H2O)(3)](n) (1, H(4)AQTC = anthraquinone- 1,4,5,8-tetracarboxylic acid) has been prepared under hydrothermal conditions and characterized by single-crystal X-ray diffraction, elemental analysis, infrared spectroscopy and thermogravimetric analysis. Two quinone oxygen atoms and all carboxylate oxygen atoms of AQTC(4-) are involved in coordination. Two equivalent barium ions are mainly linked by carboxylate oxygen atoms into a dimer. Neighbouring dimers are further connected by the AQTC(4-) ligand through carboxylate oxygen atom, leading to a 1-D chain structure. Every two adjacent chains are mainly further connected by face carboxylate oxygen atoms and water molecule, generating a two-dimensional layer structure. Such 2-D layer structures are connected with O(6) and O(6C) atoms from water molecules to form a 3-D structure. In addition, luminescent properties of 1 are also investigated.
