The crystal structure of the 1 : 1 adduct of N-methylaniline with 5-nitrofuran-2-carboxylic acid has been determined by single-crystal X-ray diffraction. Crystals are monoclinic, space group P21/c with Z 4 in a cell of dimensions a 8·467(5), b 6·106(2), c 23·95(1) Å, β 94·48(3)°. The molecules associate in a tetrameric, proton-transfer formation which has potential as a new supramolecular synthon.

The chloropnictines (η-C5Me5)2AsCl (1), (η-C5Me5)2SbCl (2), and (η-C5Me5)2BiCl (3) have been prepared by treatment of the appropriate element trichloride with LiC5Me5. X-ray crystallographic assays establish that in the case of 1, both C5Me5 rings are attached to As in an η1(σ) fashion. In 2 and 3, the C5Me5 rings are π delocalized and feature tri- and pentahapto ring binding, respectively, to the group 15 element. Conversion of 1 and 2 to the salts [As(η-C5Me5)2][AlCl4] (4) and [Sb(η-C5Me5)2][AlCl4] (5) was effected by reaction with the stoichiometric quantity of Al2Cl6. The X-ray crystal structure of 4 is surprisingly complex and features four independent ion pairs in the asymmetric unit with a variety of hapticities for the π-bonded C5Me5 rings. The structure of the stibocenium cation of 5 involves bis(η4) attachment of the π-bonded C5Me5 rings.Key words: main group metallocenes, arsocenium cations, stibocenium cations, group 15 pentamethylcyclopentadienyl chlorides.

The title compound [Na(15-crown-5)][C6H5–C(NSiMe3)2SnCl3F] is synthesized by the reaction of sodium fluoride with Ph—C(NSiMe3)2SnCl3 in acetonitrile solution in the presence of 15-crown-5 as white, moisture-sensitive crystals. The complex is characterized by its IR spectrum as well as by an X-ray structure determination. Space group P212121 Z = 4, 4897 observed independent reflexions, R = 0.094. Lattice dimensions at 20°C: a = 1065.7(2), b = 1431.0(2), c = 2325.6(3) pm. The compound forms ion pairs with a bent Sn–F–Na bridge (bonding angle 119.0(5)°) and distances Sn–F of 196(1) and Na–F of 232(1) pm. The tin atom is in a distorted octahedral environment defined by the two N atoms of the symmetrically coordinated amidinato ligand, by three chlorine atoms, and by the fluorine ligand; the latter is in a trans-position relative to one of the nitrogen atoms.
