In the crystals of [Ca(H2O)(5)][Cr(Ida)(2)](2) center dot 4H(2)O (triclinic symmetry, a = 10.1056(10) angstrom, b = 13.0077(11) angstrom, c = 13.1185(13) angstrom, alpha = 70.186(11)degrees, beta = 81.248(11)degrees, gamma = 78.996(11)degrees, Z = 2, space group P (1) over bar) cyclic centrosymmetric tetramers are present. In them calcium ions are bonded to oxygen atoms of the carboxyl groups of two octahedral complex cis(N)-[Cr(Ida)(2)](-) ions (Ida is the iminodiacetic acid anion). The O atoms of five water molecules complete the Ca atom environment to a distorted pentagonal bipyramid. Isolated [Cr(Ida)(2)](-) ions of a similar structure neutralize the positive charge of tetramers.
