Triethyl-ammonium hexa-µ(2)-acetato-κO:O'-diacetato-κO-aqua-µ(3)-oxido-triferrate(III) toluene monosolvate.

The title compound, (C(6)H(16)N)[Fe(3)(CH(3)CO(2))(8)O(H(2)O)]·C(7)H(8), was serendipitously crystallized from a reaction of disilanol with iron(II) acetate. The trinuclear acetatoferrate(III) anion has a triethyl-ammonium cation as the counterion. The three Fe atoms lie on the vertices of a regular triangle and are octa-hedrally coordinated. The complete coordination of the anion includes shared ligands among the three metal ions: a central tribridging O atom and six bidentate bridging acetyl groups. The six-coordinations of two of the metal ions are completed by a monodentate acetate ligand, whereas that of the third metal ion is completed by a water mol-ecule. The uncoordinated triethyl-ammonium cation is involved in N-H⋯O hydrogen bonding to a singly coordinated acetyl group. The coordinated aqua mol-ecule is involved in bifurcated O-H⋯O hydrogen bonding. C-H⋯O inter-actions are also observed. The toluene solvent molecule is disordered over two sets of sites in a 0.609 (11):0.391 (11) ratio.

trans-Carbonyl-chloridobis[tris-(4-chloro-phen-yl)phosphane]rhodium(I) acetone monosolvate.

The title compound, trans-[RhCl(C(18)H(12)Cl(3)P)(2)(CO)]·C(3)H(6)O, contains an Rh(I) atom in a distorted square-planar coordination with a P-Rh-P angle of 175.27 (2)° and Rh-P bond lengths of 2.3127 (4) and 2.3219 (4) Å. The rhodium complexes link each other through weak inter-molecular contacts between the acetone methyl groups and the carbonyl O atom. Inter-actions between the acetone solvent mol-ecule and the Cl-Rh unit results in a reduced P-Rh-Cl angle of 86.675 (15)°.
