[ErC6H3(COO)3(H2O)3] ·H2O, Mr = 446. 5, orthorhombic, space group P212121, a = 6. 072(1), b = 9.530(2), c=19. 844(4)(?) , 7 = 1148.3 (4)(?)3, Z=4, Dc = 2.58g/cm3, F(000) = 852, μ(Mo Kα) = 76. 4/cm. The final R = 0. 044 and Rw = 0. 046 for 1570 observed unique reflections with I> 3σ(I). The erbium ion is nine-coordinated by six oxygen atoms from four 1, 2, 4-benzenetri-carboxylates and three from three aqua molecules, forming a mpnocapped square an-tiprism. The Er -O distances fall in the range of 2. 31 - 2. 66 A with an average of 2. 42(?). The structures of title complex and [13] show a similar three dimensional polymeric network.
