Triphenyl{(E)-4-[4-(phenyldiazenyl)phenyl]-4H-1,2,4-triazol-1-yl}boron

In the title compound, C32H26BN5 or [(C14H11N5)B(C6H5)3], the B atom is approximately tetra­hedrally coordinated. The diazo unit is in a trans conformation, which is generally more stable than a cis one for aromatic azo compounds. The crystal structure features very weak C—H⋯π inter­actions. The dihedral angles between the central benzene ring and the terminal rings in the heterocycle are 62.64, 73.54 and 61.60°

Dichlorido[1-(8-quinolylimino­meth­yl)-2-naphtholato]iron(III)

The FeIII ion in the title complex, [FeCl2(C20H13N2O)], has a distorted square-pyramidal coordination formed by one O atom and two N atoms from a tridentate 1-(8-quinolylimino­meth­yl)-2-naphtholate ligand and two Cl atoms. In the crystal structure, mol­ecules form a column structure along the a axis through π–π stacking inter­actions, with centroid–centroid distances of 3.657 (1) and 3.818 (2) Å. Weak C—H⋯Cl inter­actions are observed between the columns
