Cover illustration: Salts of weakly coordinating anions, such as [Al(hfip)4]− [tetrakis(1,1,1,3,3,3-hexafluoropropan-2-olato)aluminate; hfipH = hexafluoroisopropanol], have recently emerged as state-of-the-art electrolytes for rechargeable multivalent metal batteries. Bis(dimethoxyethane-1κ2O,O′)pentakis(1,1,1,3,3,3-hexafluoropropan-2-olato)-2κ3O,3κ2O-μ-hydroxido-1:3κ2O-μ3-oxido-1:2:3κ3O-magnesiumdialuminium formed upon partial hydrolysis of the complex [Mg(dme)3][Al(hfip)4]2 (dme = dimethoxyethane), which is a promising electrolyte salt for magnesium batteries.

metal-organic compounds
A divalent copper one-dimensional ribbon copper(II) coordination polymer, with 1,3-bis(pyridin-3-yl)urea and succinate ligands, was structurally characterized by single-crystal X-ray diffraction.
The title compound contains octahedrally coordinated NiII ions ligated by adamantane-1,3-dicarboxylate and N-(pyridin-3-yl)isonicotinamide ligands forming coordination polymer layers with a (4,4) grid topology.
In situ lactonization of 2-carboxycinnamic acid to form bis(1,3-dihydro-3-oxo-1-isobenzofuranacetate (dibf) resulted in the the crystallization of [Cu(dibf)(edn)(H2O)2]n coordination polymer chains [edn = N,N′-(ethane-1,2-diyl)dinicotinamide].
The title complex was formed as a partial hydrolysis product of [Mg(dme)3][Al(hfip)4]2 (dme = dimethoxyethane and hfipH = hexafluoroisopropanol), a promising electrolyte salt for magnesium batteries.
The title compound contains five-coordinate ZnII ions intermediate between square-pyramidal and trigonal–bipyramidal coordination geometries. The ZnII ions are connected by 2-carboxycinnamate (cca) ligands and N,N′-bis-(pyridine-4-carboxamido)piperazine (4-pcap) ligands to construct a non-interpenetrated, tri-periodic coordination polymer with embedded [Zn2(OCO)2] dimeric units. Treating these as six-connected nodes reveals an overall (41263) pcu topology.
The divalent nickel compound {[Ni(ceb)(bpmp)(H2O)2]n, (ceb is (4-(carboxyethyl)benzoate; bpmp is 1,4-bis(pyridin-4-ylmethyl)piperazine) crystallizes as a fivefold interpenetrated tri-periodic coordination polymer without co-crystallized species.
Centrosymmetric [Cr2(OAc)4(THF)2] consists of two CrII atoms that are bridged by four acetate ions to yield a typical paddle-wheel structure. Furthermore, each chromium atom bears an axially bound THF ligand to give a square-pyramidal coordination.
A divalent copper tri-periodic coordination polymer with no co-crystallized species and underlying pcu topology, {[Cu2(glu)2(3-dpu)]n, was prepared and structurally characterized by single-crystal X-ray diffraction.
organic compounds
In the title compound, [24]dithiaamethyrin(1.0.0.1.0.0); C50H44Cl4N4S2, the macrocycle can be described as a highly planar structure with a mean-plane deviation (MPD) value of 0.0416 Å. The molecular conformation is stabilized by two intramolecular N—H⋯N interactions. In the crystal, molecules are also linked via C—H⋯π interactions forming a three-dimensional network.
In the crystal structure of the title bis-urea derivative, the host molecules are linked by N—H⋯O=C hydrogen bonds and C—H⋯O contacts with
