In the title compound, [Mo(C(44)H(28)N(4))(NO(3))O]·C(6)H(6), the porphyrin ring is centrosymmetric. The Mo atom, oxide ion and nitrate ion are equally disordered over two sites, such that the Mo atom is displaced by 0.366 (1) Å towards the oxide ion from the 24-atom mean plane of the porphyrin, and also makes a long Mo-O bond to a nitrate O atom. A centrosymmetric benzene solvent mol-ecule is ...

The title compound, [Au(III)Cl(2)(C(12)H(12)N(2))](2)[Au(III)Cl(4)][Au(I)Cl(2)], contains three distinct types of Au atom. In the cation, the Au(III) atom is four-coordinated in a distorted square-planar arrangement by an N,N'-bidentate 5,5'-dimethyl-2,2'-bipyridine ligand and two terminal Cl atoms. In the [AuCl(4)](-) anion, the centrosymmetric Au(III) atom has a square-planar coordination. Th...

The title solvate, C20H14N4O4S·C3H7NO, comprises a stereogenic centre but the centrosymmetric space group causes the presence of the racemate in the crystal. The spiro-joined fragments are almost orthogonal, with a dihedral angle of 86.8 (2)° between the mean planes of the pyrane ring and the dihydroindolone ring system. The atoms of the indolinone bicycle are coplanar, with an r.m.s. deviation...

The asymmetric unit of the title compound, C(14)H(8)N(2)O(8)·2C(3)H(7)NO or L·2DMF (DMF = N,N-dimethyl-formamide), contains one half of the centrosymmetric mol-ecule L and one solvent mol-ecule, which is disordered between two orientations in a 0.555 (4):0.445 (4) ratio. Inter-molecular O-H⋯O hydrogen bonds link one L and two DMF mol-ecules into a centrosymmetric hydrogen-bonded cluster. The cr...

In the title compound, C(26)H(20)ClNO(2), the quinoline ring system is approximately planar with a maximum deviation of 0.028 (2) Å and forms a dihedral angle of 73.84 (5)° with the phenyl ring. Two neighbouring mol-ecules are arranged into a centrosymmetric dimer through a pair of inter-molecular C-H⋯Cl inter-actions. A pair of inter-molecular C-H⋯O hydrogen bonds link two methoxy-phenyl group...
