catena-Poly[[aqua­copper(II)]-μ-hydrox­ido-μ-naphthalene-1-carboxyl­ato-κ²O:O′]: effect of a bulky aromatic skeleton in self-assembly

In the title coordination polymer, [Cu(C₁₁H₇O₂)(OH)(H₂O)]_n, the Cu^II center is five-coordinated by two O atoms from two different naphthalene-1-carboxyl­ate (L) ligands, one O atom from one coordinated water mol­ecule and two O atoms from two hydroxide anions. L ligands and hydroxide anions jointly bridge adjacent Cu^II centers to generate a one-dimensional chain along the b-axis direction. The results reveal that the steric bulk of the naphthalene ring system in L may play an important role in the formation of the title complex.

9,9′-Biacridine N,N′-dioxide: a novel potential bridging ligand bearing the bulky acridine N-oxide skeleton

The title compound, C₂₆H₁₆N₂O₂, is a potential linear bridging O-donor ligand comprising bulky acridine N-oxide ring systems. Weak inter­molecular C—H...O hydrogen-bonding inter­actions link adjacent mol­ecules to form extended chains. The structure also contains inter­molecular C—H...π inter­actions.
