摘要

The neutral mer-triaquatrichloroiron (III) molecule, mer-[(H2O)(3)FeCl3], has been structurally defined, co-crystallized with a pair of organic-cation/chloride salts, from hydrochloric acid solution in each case. The array {[HN(CH2CH2)(3)NH]Cl-2}-{mer-[(H2O)(3)FeCl3]}, (1) has been previously described in a room-temperature study in terms of orthorhombic Pnma symmetry;, here, at low-temperature (ca. 153 K), the description is in terms of P2(1)2(1)2(1), with the complex of quasi-m symmetry Full M symmetry is achieved in the second complex, {[H2N(CH2CH2)(2)NH2]Cl-2}{mer-[(H2O)(3)FeCl3]}, (2) which crystallizes in space group P2(1)/m. Fe-Cl and Fe-O(H-2) are very tightly ranged in 1, < > 2.3359(6), 2.051(5) angstrom, respectively, less so in 2 (2.326(1), 2.340(1); 2.049(2)-2.080(2) angstrom), despite strong hydrogen-bonding in the lattice between the hydrogen atoms of the coordinated water molecules and the uncoordinated chloride ions. A redetermination of the structure of FeCl3 center dot 6H(2)O (3), trans-tetraquadichloroiron(III) chloride dihydrate, is also recorded; at 100 K,Fe-Cl,O are 2.2830(4), 2.0543(9) angstrom.
