The asymmetric unit of the title complex, [Sb(C44H28N4)Cl2][Sb2Cl8]0.5·CH2Cl2, is composed of a SbV complex cation wherein the Sb atom is hexacoordinated by four N atoms of the pyrrole rings of the tetraphenylporphyrinate (TPP) ligands and two chloride ions, a half di-μ-chlorido-bis[trichloridoantimonate(III)] counter-anion and a dichloromethane solvent molecule. In the cation, the average Sb—N distance is 2.066 (2) Å, while the Sb—Cl distances are 2.3410 (11) and 2.3639 (12) Å. The central unit of the cation, SbN4C20, is far from being planar, with deviations of atoms from the least-squares plane ranging from −0.110 (4) to 0.124 (4) Å. The Sb—Cl distances in the anion, which is located about an inversion center, lie in the wide range 2.3715 (13)–2.7489 (13) Å, the longest distances being between the Sb and bridging Cl atoms. The crystal structure is stabilized by intermolecular C—H
Cl interactions involving the cations, the anions and the solvent molecules. The solvent molecule is disordered over two orientations in a 0.901 (13):0.099 (13) ratio.

The title complex, [Ce(C2H6OS)8]2[Mo6O19]3·4C2H6OS, was obtained as a byproduct of the reaction of [(C4H9)4N]2[Mo6O19] with Ce(NO3)3·6H2O and phthalic acid in dimethylsulfoxide solution. The asymmetric unit consists of a complex [Ce(C2H6OS)8]3+ cation, one and a half of the Lindqvist-type [Mo6O19]2− polyanions and two dimethylsulfoxide solvent molecules; the half polyanion lies on an inversion center. The Ce3+ ion is coordinated by eight dimethylsulfoxide ligands through the O atoms in the form of a distorted square antiprism. The Ce—O bond lengths range from 2.429 (6) to 2.550 (5) Å. The cohesion of the structure is ensured by SO [3.115 (6), 3.242 (10) and 3.12 (3) Å], OO [3.037 (10) Å] and C—HO interactions between cations and anions. The S and C atoms of a dmso ligand are disordered over three sites in a 0.45:0.30:0.25 ratio. The dimethylsulfoxide solvent molecules are highly disordered and could not be modelled successfully; their contribution was therefore removed from the refinement using the SQUEEZE routine in PLATON [Spek (2009). Acta Cryst. D65, 148–155]. Potential solvent-accessible voids of 500.0 Å3 occur in the crystal structure.

In the title compound, [K(C18H36N2O6)][Co(NCO)2(C44H28N4)]·0.5C6H5Cl or [K(2,2,2-crypt)+][CoIII(NCO)2(TPP)−]·0.5C6H5Cl, the CoIII ion is octahedrally coordinated by two axial N-bonded NCO− anions and four pyrrole N atoms of the porphyrin. There is a major ruffling distortion of the porphyrin: the dihedral angles between trans pyrrole rings are 34.32 (14) and 34.72 (14)°. The potassium ion is coordinated by the six O atoms and two N atoms of the cryptand-222 molecule and a weak K—O [3.407 (3) Å] bond to one of the cyanate O atoms also occurs. The packing also features weak C—HO and C—Hπ interactions. The contribution to the scattering of the disordered chlorobenzene solvent molecules was removed with the SQUEEZE function in PLATON [Spek (2009). Acta Cryst. D65, 148–155].

The asymmetric unit of the title compound, [Cd2Na2(N3)2(C44H28N4)2(C12H24O6)2], consists of one half of the dimeric complex; the tetranuclear molecule lies about an inversion centre. The CdII atom is coordinated by the four pyrrole N atoms of the 5,10,15,20-tetraphenylporphyrinate ligand and one N atom of the axial azide ligand in a square-pyramidal geometry. The azide group is also linked to the NaI atom, which is surrounded by one 18-crown-6 molecule and additionally bonded to a second 18-crown-6 molecule trans to the azide group. The porphyrin core exhibits a major doming distortion (∼40%) and the crystal structure is stabilized by weak C—Hπ interactions. The molecular structure features weak intramolecular hydrogen bonds: two O—HO interactions within the 18-crown-6 molecule and one C—H(18-crown-6)N(azido) contact.

In the title compound, C16H16Cl2O2, the dihedral angle between the two rings is 52.65 (10)°. The two Cl atoms are trans to one another being displaced by 1.644 (5) and −1.664 (4) Å from the plane of the benzene ring. Except for the two Cl atoms and the C atoms of the ring of the benzyloxy group, all the other atoms of the compound lie in the same plane [maximum deviation = 0.056 (3) Å]. In the crystal, no significant intermolecular interactions are observed.
