Bis(N,N′-diphenyl­benzamidinium) fumarate

The crystal structure of the title compound, 2C19H17N2 +·C4H2O4 2−, consists of centrosymmetric trimers built up of two crystallographically independent N,N′-diphenyl­benzamid­in­ium cations and one fumarate dianion, which is located on a centre of inversion. The components of the trimers are linked by N—H⋯O hydrogen bonding. In the cation, the outer rings make dihedral angles of 53.66 (5) and 78.38 (5)° with the central ring. The two outer rings make a dihdral angle of 81.49 (5)°

cis-Bis­(2,2′-bipyrid­yl)dicyanato­cobalt(II)

In the title complex, [Co(NCO)2(C10H8N2)2], the Co atom is coordinated by four N atoms from two 2,2′-bipyridyl ligands and two N atoms from two cyanate anions in a distorted octa­hedral geometry. The Co atom lies on a twofold rotation axis. The average Co—N bond length is 2.126 (7) Å. Weak inter­molecular C—H⋯O inter­actions lead to the formation of a three-dimensional network

Dipotassium 4,4′-(hexane-3,4-di­yl)bis­(benzene­sulfonate) dihydrate

The anion of the title compound, also called sygethin dihydrate, 2K+·C18H20O6S2 2−·2H2O, has crystallographic inversion symmetry. The K+ cation is surrounded by eight O atoms in a distorted cubic coordination geometry, forming extended K—O—S networks. There are also O—H⋯O hydrogen bonds

A Call to Action for Gender Equity in Climate Leadership.

Climate action is not advancing quickly enough to prevent catastrophic harm. Understanding why might require looking at existing leadership structures and the inequitable gender representation therein. Critically examining dominant power structures could pave the way toward more comprehensive, innovative, and expedient environmental solutions-and we argue that elevating women's climate leadership is key to safeguarding planetary health. Women have historically been left out of climate science and governance leadership. Women are disproportionately impacted by the health effects of climate change, particularly in Indigenous and low- and middle-income settings. Therefore, our call for women's climate leadership is both an issue of justice and a matter of effectiveness, given evidence that inclusive leadership rooted in gender justice leads to more equitable outcomes. Here, we present evidence for why gender equity in climate leadership matters along with considerations for how to attain it across sectors and stakeholders

Spontaneous Cocrystal Hydrate Formation in the Solid State: Crystal Structure Aspects and Kinetics

Kinetics of anhydrous cocrystal hydration and that of cocrystal monohydrate formation from starting compounds in the solid state are studied as a function of RH and time. The propensity of the anhydrate to hydration is related to the crystal structures of anhydrous and hydrated forms
