The title binuclear compound, [Cu2(CH3COO)4(C6H4N2)2], lies about an inversion center, with the CuII cation bridged by four acetate anions and coordinated by a pyridine N atom in a distorted square-pyramidal geometry. The Cu...Cu distance is 2.5997 (15) Å. In the crystal, mol­ecules are linked by weak C—H...O and C—H...N hydrogen bonds into a three-dimensional supra­molecular architecture. The crystal studied was a non-merohedral twin with a minor twin component of 4.1 (1)%.

There are two independent mol­ecules in the asymmetric unit of the title compound, C10H8INO2, which differ in the degree of planarity. The iodo­indoline-2,3-dione skeleton of mol­ecule 1 is essentially planar [mean deviation = 0.003 (2) Å for the nine non-H atoms of the indoline core, with a maximum deviation of 0.033 (1) Å for the I atom]. The I atom and O atom in the 3-position of mol­ecule 2 deviate by 0.195 (1) and 0.120 (2) Å, respectively, from the least-squares plane through the nine non-H atoms of the indoline core. Mol­ecules 1 and 2 are roughly coplanar, the mean planes through their cores making a dihedral angle of 6.84 (1)°. This coplanarity results in a layer-like structure parallel to (6,11,17) in the crystal, the distance between adjacent least-squares planes through the cores of mol­ecules 1 and 2 being 3.37 (1) Å. In such a layer, mol­ecules 1 and 2 are linked by C—H...O hydrogen bonds, forming chains along [11-1]. The chains are further coupled to construct a kind of double-chain structure via I...O inter­actions [3.270 (2) Å].

In the title compound, C12H12N2O2, synthesized by ammonolysis of 3-phenyl­isoxazole-5-carbonyl chloride in di­chloro­methane, the dihedral angle between the isoxazole ring and the phenyl ring is 14.05 (7)°. In the crystal, centrosym­metrically related mol­ecules are linked into dimers by pairs of C—H...O hydrogen bonds, generating rings of graph-set motif R22(10).

In the title compound, C11H9NO3, the dihedral angle between the isoxazole and phenyl rings is 19.79 (12), while the ester group is inclined to the isoxazole group by 12.14 (6)°. In the crystal, mol­ecules are linked by C—H...O hydrogen bonds, forming layers lying parallel to (010).

The title compound, [Al(CH3)2(C30H41O)] is synthesized by the reaction of 2,6-di-adamantyl-4-tert-butyl-phenol with Al(CH3)3 in a nitro­gen atmosphere. In the mol­ecule, the coordination geometry around the AlIII atom is slightly distorted C2O trigonal (the sum of the bond angles subtended at Al atom being 359.9°), which is rarely reported for organometallic aluminium compounds. The coordination plane is approximately perpendicular to the benzene ring [the dihedral angle = 87.73 (16)°]. There is no inter­molecular hydrogen bonding in the crystal structure.
