Summary: In the past decade, the use of divergent 4,2':6',4''- and 3,2':6',3''-terpyridine ligands as linkers and/or nodes in extended coordination assemblies has become popular. However, only a few of the 45 isomers of terpyridine have been utilized in such structures. This overview focuses on coordination polymers and networks containing terpyridine isomers with zinc(II) and cadmium(II), examining structural details, reproducibility, and competitive product formation. A lack of systematic investigations into these systems is highlighted.

Summary: The use of renewable energy is crucial for the future of the Earth, with solar energy being the primary source to meet the growing global energy demand. Dye-sensitized solar cells (DSCs) have emerged as a mature technology in the sustainable energy market, and this review focuses on the use of first row d-block metal coordination compounds, specifically copper, iron, and zinc, as dyes in DSCs to replace the critical raw material ruthenium. The main challenge in these DSCs is to enhance their photoconversion efficiencies which are currently lower compared to those containing ruthenium-based dyes. Advancements have been made in the development of alternative redox mediators, particularly cobalt and copper complexes, which have achieved open circuit voltage values exceeding 1000 mV when coupled with suitable dyes.

Summary: This article describes the synthesis and characterization of two tritopic ligands containing a 2,2':6',2''-terpyridine (tpy) metal binding domain and either a 3,2':6',3''- or a 4,2':6',4''-tpy domain. The synthetic routes involved the [Pd(dppf)Cl2]-catalyzed coupling of a boronic ester-functionalized 2,2':6',2''-tpy with bromo-derivatives of 3,2':6',3''-tpy or 4,2':6',4''-tpy. The tritopic ligands preferentially bind Fe2+ ions and form iron(II) complexes with two peripheral 3,2':6',3''-tpy or 4,2':6',4''-tpy metal binding sites.

Summary: [M(bpy)(3)](q)(+) cations are coordination entities with chelating bidentate N,N'-donor ligands, exhibiting delta or lambda enantiomers. The crystal supramolecular chemistry of [M(bpy)(3)](q)(+) cations is mainly controlled by cation-anion interactions and weaker non-covalent interactions. Analysis of [M(bpy)(3)](q)(+) salts in the Cambridge Structural Database (CSD) reveals a common motif of homochiral cation sheets forming cavities for anion accommodation. A common motif identified is a hexagon of six cations with anions either in the center or lying above and/or below the centroid.

Summary: Analysis of compounds with a {M(tpy)X-3} motif in the Cambridge Structural Database (CSD) reveals 17 isostructural mononuclear [M(tpy)X-3] compounds without solvent. Face-to-face p-stacking of pyridine rings and C-H3/H3' ellipsis X hydrogen bonding are equally important. The presence of bifurcated Cl ellipsis H3/H3' interactions is a recurring packing feature in compounds containing the {M(tpy)X-3} unit, complemented by Cl ellipsis H5'/H3 interactions in some cases. Octahedral [M(tpy)F-3] complexes crystallize as hydrates with strong F ellipsis H-OH hydrogen bonding dominating the crystal packing.

Summary: Packing motifs in structurally characterized cis-[M(bpy)(2)X-2] coordination compounds were investigated. The compounds can be divided into two classes: non-solvated cis-[M(bpy)(2)X-2] moieties and those with additional lattice molecules. A recurring packing motif involving intermolecular p-stacking of bpy ligands and CHbpy...X contacts was observed, but slippage of stacked bpy units reduced the effectiveness of face-to-face interaction, making CHbpy...X contacts the dominant crystal-packing interaction. The prevalence of dimeric units versus 1D chains in the solid state was described.

Summary: The activation of SrTiO3 and BaTiO3 nanoparticles using H2O2 or aqueous HNO3 followed by functionalization with a phosphonic acid anchoring ligand and metal complex has been investigated. The photocatalytic activity of the functionalized nanoparticles for H-2 generation from water was compared to TiO2 nanoparticles. pH was found to play a crucial role during surface complexation. Extensively functionalized SrTiO3 or BaTiO3 nanoparticles showed better performance for water reduction than TiO2 nanoparticles.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
