The structure of catena-((μ8-benzene-1,2,4,5-tetracarboxylato)-triaqua-calcium(II)-copper(II)) (I) was determine by X-ray crystallography. There is half of one benzene-1,2,4,5-tetracar-boxylate tetra-anion (BTA4−), each half Cu(II) and Ca(II) dications, and one and a half coordinated water molecules in its asymmetric unit. The compound crystallizes in the monoclinic C2/c space group and was characterized as follows: a = 14.1365(13)Å, b = 13.2077(12)Å, c = 8.8865(8)Å, b = 126.365(3)°, V = 1336.1(2)Å3, Z = 4, T = 150(2)K. The crystal structure was solved by direct methods and refined by full-matrix least-squares on F2 to final values of R1 = 0.0779 and wR2 = 0.1666.
