Forthcoming article in Acta Crystallographica Section E Crystallographic Communications
Acta Crystallographica Section E: Crystallographic Communications is the IUCr's popular open-access structural journal. It provides a simple and easily accessible publication mechanism for inorganic, metal-organic and organic crystal structure determinati
Crystal structures of 2′-benzoyl-1′-(4-methylphenyl)-1,1′,2,2′,5′,6′,7′,7a′-octahydrospiro[indole-3,3′-pyrrolizin]-2-one and 2′-(4-bromobenzoyl)-1′-(2-chlorophenyl)-1,1′,2,2′,5′,6′,7′,7a′-octahydrospiro[indole-3,3′-pyrrolizin]-2-one
The chemical modifications in terms of changes in substituents in the title compounds have not affected the type nor strength of two defining intermolecular interactions present in both crystal structures.
Crystal structure of N,N,N-triethylhydroxylammonium chloride
The cation and anion in N,N,N-triethylhydroxylammonium chloride are linked by an O—H⋯Cl hydrogen bond. The extended structure displays C—H⋯Cl and C—H⋯O hydrogen bonds, resulting in layers lying parallel to the (100) plane: further C—H⋯Cl contacts connect the sheets into a three-dimensional network.
Crystal structure of bis[μ-1,4-bis(diphenylphosphanyl)butane-κ2P:P′]bis[(3,4,7,8-tetramethyl-1,10-phenanthroline-κ2N,N′)copper(I)] bis(hexafluoridophosphate) dichloromethane disolvate
The crystal structure of a dinuclear copper(I) complex bearing bridging 1,4-bis(diphenylphosphanyl)butane and 3,4,7,8-tetramethyl-1,10-phenanthroline ligands is described.
Crystal structure of rac-2,3-diphenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one 1-oxide
In the title compound, the thiazine ring exhibits an envelope conformation, with the S atom forming the flap of the envelope. In this racemate crystal, homochiral molecules form slabs parallel to (010) of thickness b/2 which then stack with alternating chirality in the b-axis direction. The stacking is aided by edge-to-face interactions between the phenyl rings of racemic molecules.
Formation and structure of the first metal complexes comprising amidinoguanidinate ligands
The first metal complexes comprising amidinoguanidinate ligands have been prepared and structurally characterized, namely bis[μ-N,N′,N′′,N′′′-tetraisopropyl-1-(1-butylamidinato)guanidinato-κ3N1,N2:N2) bis[(tetrahydrofuran)lithium] and [bis(tetrahydrofuran)lithium]-di-μ-chlorido-[N,N′,N′′,N′′′-tetracyclohexyl-1-(1-butylamidinato)guanidinato-κ2N1,N2](N,N′-dicyclohexyl-1-butylamidinato-κ2N1,N2)holmate(III).
