Construction of a three-dimensional network with open channels via Ag–Ag and π–π interactions between nanoscale sized molecular chains

The reaction of Ag₂O with pybz (pybz=4-(4-pyridyl)benzoate) gave the monomer compound [Ag(pycz)(H₂O)], 1. Using 4,4′-bipyridyl (bpy) as a spacer to increase the length of the monomer resulted in the nanosized molecular chain compound [Ag₂(pybz)₂(bpy)], 2. In 1, two monomers [Ag(pycz)(H₂O)] are combined together through Agπ, ππ and Ag(CC) interactions to form a dimer, with the distances of 3.34, 3.56 and 3.18 Å, respectively. In 2, the [Ag₂(pybz)₂(bpy)] units are held together via ππ (3.4–3.5 Å) interactions resulting in a 3D network with 1D open channels.

Tris(1,10‐phenanthroline‐N,N′)chromium(III) triperchlorate hydrate

The structure of the cation in [Cr(C₁₂H₈N₂)₃](ClO₄)₃·H₂O consists of the Cr atom bonded to the N atoms of the three 1,10‐phenanthroline (phen) ligands, resulting in a distorted octahedral arrangement with the six Cr—N distances ranging from 2.040 (4) to 2.055 (4) Å. One of the perchlorate anions is disordered and is located around two special positions.
