The dihedral angles between the P—Rh—P and the X—Rh—X planes (X is the centroid of a double bond) are 14.7 (1), 14.8 (1) and 15.3 (1)°. The structure exhibits disorder of one cyclooctadiene ligand as well as one BF4 anion.The title compound, [Rh(C DOI: 10.1107/S1600536810019859/im2198Isup2.hkl            Structure factors: contains datablocks I.

The other two imino N atoms act as hydrogen-bond acceptors from phenolate OH groups. The toluene solvent molecule is disordered about a centre of inversion.In the toluene hemisolvated tripodal tris(2-aminoethyl)amine Schiff base, C DOI: 10.1107/S1600536809002906/bt2855Isup2.hkl            Structure factors: contains datablocks I.

Two Cl atoms lying above and below the plane formed by these four N atoms interact weakly with the Cu atom [Cu—Cl = 2.7870 (7) Å]. The trans 2,5-bis(4-pyridyl)-1,3,4-oxadiazole ligands act as bridging ligands, linking adjacent Cu atoms and forming a one-dimensional coordination polymer. Two anilines coordinate with each Cu atom as terminal groups. The structure contains two classical N—H⋯Cl and two non-classical C—H⋯Cl hydrogen bonds.In the title compound, [CuCl DOI: 10.1107/S1600536809054191/pv2245Isup2.hkl            Structure factors: contains datablocks I.

The Fe atom is six-coordinated by three phenolic O and three imine N atoms from three Schiff base ligands in an octahedral geometry.The title complex, [Fe(C DOI: 10.1107/S1600536808014165/sj2500Isup2.hkl            Structure factors: contains datablocks I.

Each CuII atom is bound to two N atoms and one O atom of the pyridinedicarboxylate (PDA) ligand in a tridentate manner, one N atom of the pyridine molecule and two bridging carboxylate O atoms of adjacent PDA ligands, leading to a linear one-dimensional chain running along the c axis. These chains are further assembled via weak C—H⋯O and π–π interactions into a three-dimensional supramolecular network structure. The centroid–centroid distance between the π–π interacting pyridine rings is 3.9104 (13) Å. The two N atoms are trans to each other with respect to Cu.In the title compound, [Cu(C DOI: 10.1107/S1600536809005212/is2384Isup2.hkl            Structure factors: contains datablocks I.

The complex monoclinic structure of the first arsenide to form with this type features chains made of corner-sharing ZnAs4 tetrahedra, separated by Eu atoms. There are a total of 15 unique positions in the asymmetric unit. Except for one Eu atom with site symmetry 2/m, all atoms are located on mirror planes. An usual aspect of the structure are some Zn—As distances, which are much longer than the sum of the covalent radii, indicating weaker interactions.The title compound, Eu DOI: 10.1107/S1600536810006938/wm2307Isup2.hkl            Structure factors: contains datablocks I.
