The mononuclear title complex, [Fe(CF3O3S)(C5H7O2)2(C4H8O)] or [Fe(acac)2(OTf)(THF)] (acac = acetylacetonate; OTf = trifluoromethanesulfonate; THF = tetrahydrofuran), (I), consists of one six-coordinate Fe3+atom in a slightly distorted octahedral environment [Fe—O bond-length range = 1.9517 (11)–2.0781 (11) Å]. The triflate ligand was found to be disordered over two sets of sites, with a site-occupancy ratio of 0.622 (16):0.378 (16). Weak intermolecular C—H...O and C—H...F hydrogen-bonding interactions generate a two-dimensional supramolecular structure lying parallel to (100). This is only the second crystal structure reported of a mononuclear bis(acetylacetonato)iron(III) complex.

The title complex, [Ni(C10H8N3O2)2]·CH3OH, is a mononuclear nickel(II) compound containing two di-2-pyridylamine N,N′-dioxide (dpa dioxide) ligands that are nearly perpendicular to each other. The NiII ion of the complex has a distorted octahedral environment with the equatorial plane formed by an N atom from each amine group and two O atoms of one ligand, while the axial positions are occupied by two O atoms of the second ligand. In the solid state, hydrogen-bonding interactions are dominant, with solvent molecules also participating in hydrogen bonding.

The title compound, {[Ag(C6H7AsNO3)(C18H15P)]·H2O}n, has been synthesized from the reaction of 4-aminophenylarsonic acid with silver nitrate, in aqueous ammonia, with the addition of triphenylphosphane (PPh3). The AgIcentre is four-coordinated by one amino N atom, one PPh3P atom and two arsonate O atoms, forming a severely distorted [AgNPO2] tetrahedron. Two AgI-centred tetrahedra are held together to produce a dinuclear [Ag2O2N2P2] unit by sharing an O–O edge. 4-Aminophenylarsonate (Hapa−) adopts a μ3-κ3N:O:O-tridentate coordination mode connecting two dinuclear units, resulting in a neutral [Ag(Hapa)(PPh3)]nlayer lying parallel to the (10\overline{1}) plane. The PPh3ligands are suspended on both sides of the [Ag(Hapa)(PPh3)]nlayer, displaying up and down orientations. There is anR22(8) hydrogen-bonded dimer involving two arsonate groups from two Hapa−ligands related by a centre of inversion. Additionally, there are hydrogen-bonding interactions involving the solvent water molecules and the arsonate and amine groups of the Hapa−ligands, and weak π–π stacking interactions within the [Ag(Hapa)(PPh3)]nlayer. These two-dimensional layers are further assembled by weak van der Waals interactions to form the final architecture.
