The structure of the title compound, [Fe(C5H5)(C10H12N2)]I, consists of a 1-(ferrocen-1-ylmethyl)-3-methylimidazolium cation which is counter-balanced by an iodide anion. The cyclopentadienyl (Cp) rings of the ferrocene unit have a slightly staggered conformation skewed from an ideal eclipsed conformation by an angle of 3.5 (6)°. The interplanar angle between the Cp and the imidazole ring is 67.94 (2)°.

In the title compound, [Ni(C9H12O2PS2)2], the NiII atom resides on an inversion center and is coordinated by four S atoms [Ni—S = 2.2328 (4) and 2.2455 (3) Å] in a distorted square-planar geometry [S—Ni—S = 88.443 (13) and 91.557 (13)°]. In the crystal, molecules related by translation in [110] are linked into chains via weak C—HO interactions. The crystal packing exhibits short intermolecular SS contacts of 3.3366 (5) Å.

The title compound, [Ni(C11H16O2PS2)2], contains a four-coordinate NiII cation with an idealized square-planar geometry. The metal atom is surrounded by two chelating isobidentate dithiophosphonate ligands in a trans or anti configuration, binding through the S-donor atoms.

The asymetric unit of the title compound, [Fe(C5H5)(C17H13N2)], contains two independent molecules whose conformations differ, especially in the 4-{(pyridin-4-yl)methylidene]amino}phenyl unit where one is flipped by almost 180°. The cyclopentadienyl rings of the ferrocene unit also exhibit different staggered conformations: in one molecule the conformation is staggered by 9.43 (2)° and in the other by 24.46 (1)° from an ideal eclipsed geometry. The plane of the benzene ring is tilted away from the ferrocene group in both molecules, with dihedral angles of 6.97 (1) and 10.30 (2)°. The benzene ring is also slightly twisted from the plane of the pyridine ring, with dihedral angles of 5.98 (2) and 6.51 (2)° in the two molecules.

The title compound, C32H29NP2S2, has two molecules in the asymmetric unit, with an r.m.s. difference of 0.218 Å in their best-fit overlay. Both molecules have a slightly distorted trigonal–planar N atom, bonded to two PV atoms and a C atom of the 4-ethylphenyl unit. The P—N—P angles of 126.34 (11) and 125.98 (11)° are larger than the four C—N—P bond angles. The two S atoms are trans to one another with respect to the P—N—P angle. The crystal structure features C—Hπ interactions. The methyl group in one of the molecules is disordered over two sets of sites, with occupancies of 0.518 (6) and 0.482 (6).
