A copper(I) coordination polymer incorporation the corrosion inhibitor 1H-benzotriazole: poly[μ₃-benzotriazolato-κ³N¹:N²:N³-copper(I)]

1H-Benzotriazole (BTAH) has been used for the first time as a ligand to construct a copper(I) coordination polymer, viz. [Cu(BTA)]_n. [Cu₂(BTA)₂]₂ secondary building units form a one-dimensional chain along the c axis.

A pillared framework coordination polymer based on the Cd₃([mu]₃-OH) unit: poly[[([mu]₄-5-amino­tetra­zolato-[kappa]⁴N¹:N²:N³:N⁴)chlorido-[mu]₃-hydrox­ido-([mu]₃-isonicotinato-[kappa]³N:O:O')­dicadmium(II)] 0.14-hydrate]

In a pillared three-dimensional Cd^II coordination polymer incorporating isonicotinate, 5-aminotetrazolate, chloride and hydroxide ligands, Cd₃([mu]₃-OH) units are laced around with a belt of chloride ligands. The belts are further connected into undulating layers via weak inter-belt Cd-Cl bonds.
