metal-organic compounds
In the crystal structure of the title compound, [Cu(ClO4)2(C13H14N2)2]n, there are two independent CuII ions, one of which occupies a crystallographic inversion center. The 1,3-bis(4-pyridyl)propane ligands bridge the CuII ions to form two independent two-dimensional sheets. In addition, two terminal perchlorate anions are coordinated to each CuII ion, resulting in distorted octahedral coordination around each CuII ion. The equatorial Cu—N bonds are in the range 2.014 (4)–2.031 (4) Å, while the long axial Cu—O distances range from 2.434 (3) to 2.548 (3) Å.

catena-Poly[[dibromozinc(II)]-μ-1,2-bis(4-pyridyl)ethane], a one-dimensional coordination polymer
In the title compound, [ZnBr2(N2C12H12)]n, the 1,2-bis(4-pyridyl)ethane ligand bridges ZnII ions to form a one-dimensional chain. The distorted tetrahedral Zn coordination is completed by two bromide ions. The crystal packing is consolidated by both intra- and interchain C—HBr interactions.
organic compounds
In the molecule of the title Schiff base compound, C30H28N2O2, the dihedral angles between the phenol rings and the adjacent dimethylbenzene rings [60.14 (11) and 77.57 (11)°] are distinctly larger than that formed by the dimethylbenzene rings [39.65 (11)°], possibly as a result of the steric hindrance of the methyl groups and the presence of intramolecular O—HN hydrogen bonds.
