Popis: Synthesis and X-ray investigation of a (GunH)2[Fe(Cit)2] single crystal are described [a = 10.327(2) A, b = 10.414(2) A, c = 11.267(2) A; β = 117.25(3)°, V = 1077.2(4) A3, P21/n, Z = 2, R(F) = 0,0239, 1196 reflections with I > 2σ(I )], where GunH is the guanidine cation (C(NH2)3)+, and Cit is the citric acid anion (C6H6O7)2−. The structure is composed of guanidinium cations and centrosymmetrical sym-cis-octahedral complex anions [Fe(Cit)2]2−. The Cit2− anion acts as a cyclic tridentate ligand and forms condensed fiveand six-membered metal-containing cycles.
