4-Methyl-N′-(2,2,2-trichloro­ethanimido­yl)benzene-1-carboximidamide

The title compound, C10H10Cl3N3, features a delocalized unsaturated N C N C N chain and strong intra­molecular N—H⋯N hydrogen bonding across the chelate ring and also intra­molecular N—H⋯Cl contacts to a CCl3-group Cl atom. The only inter­molecular contacts in the lattice are non-classical hydrogen bonds between methyl and CCl3 groups. The pseudo-six-membered ring is distinctly non-planar by virtue of rotation about the N—C bond between the carboximidamide and imine components [C—N—C—N torsion angle = −23.6 (2) °]

How can we love what we don’t know?: Children and ecological care

This article addresses the intersection of child ethics and ecological ethics, arguing that ecological care should be viewed as a shared endeavour between children and adults, where each have something to offer to and learn from the other. It is incumbent on adults to foster an embodied, intimate relationship with nature as something that is key to children’s moral development, including their morality of ecological care. This perspective also provides a model of discipleship for adults, characterised as a Rahnerian environmentally-conscious second childhood: by recollecting, observing and mimicking children’s relationship with nature, adults can learn to become like them in their care for the earth

Butyl­bis[μ-4-(2,4,6-trimethyl­phenyl­amino)pent-3-en-2-onato][4-(2,4,6-trimethyl­phenyl­amino)pent-3-en-2-onato]dimagnesium

The structure of the title compound, [Mg2(C4H9)(C14H18NO)3], contains two Mg atoms bridged by two μ2-O atoms from two of the three ketiminate ligands, while the third ketiminate is strictly chelating to one of the Mg atoms, which is thereby five-coordinate. In place of a chelating ligand, the second Mg atom is ligated by a single terminal n-butyl group and thus is four-coordinate. This is, so far, the only structurally characterized mixed magnesium ketiminate–alkyl cluster. The geometry at the first Mg atom is close to trigonal-bipyramidal with one chelating and one bridging O atom in the axial positions and two chelating N and one bridging O atom in the equatorial positions. The geometry at the second Mg atom is very distorted from tetra­hedral, with an O—Mg—C angle of 131.0 (1)°

(Z)-2,2,2-Trichloro-N 2-cyano­acetamidine

The title compound, C3H2Cl3N3, crystallizes as the Z isomer with respect to the C=N bond. The –C(NH2)=NCN functional group is effectively planar (r.m.s. deviation = 0.016 Å), with only the three Cl atoms out of the mol­ecular plane. A strong network of N—H⋯N hydrogen bonds forms dimers which are associated into ribbons in the crystal structure. Hydrogen bonding is suspected to be the cause of the near-equivalence of the formal C—N and C=N bonds (ΔCN = 0.008 Å

The C=N double-bond distance is 1.2729 (13) Å and the sum of the angles around the central N atom is 359.92°. There are short contacts [2.973 (1) Å] between the iminium C atom and the Cl- ion and between five of the C-H H atoms and the Cl- ion, of which the shortest is 2.623 (11) Å.Ye

exo-10,11-Dibromo­tricyclo­[6.3.1.02,7]dodeca-2,4,6,9-tetra­ene

The title compound, C12H10Br2, is a bridged ring system based on a homobenzonorbornadiene framework. The exo configuration of one of the Br atoms was previously assigned via NMR correlations and has now been confirmed by the geometry of the solid-state structure. The compound features a Br—C—C—Br torsion angle of 66.68 (12)°, whereby the C atoms in the calculation are respectively sp 3- and sp 2-hybridized

1-(2,4,6-Triisopropyl­phen­yl)ethanone

The title compound, C17H26O, is a di-ortho-alkyl substituted phenyl ethanone that exhibits a significant twisting of the ketone fragment relative to the aromatic ring [O—C—C—C torsion angle = 89.32 (17)°] due to steric pressure from the ortho-isopropyl groups. One ortho- and the para-isopropyl group exhibit orientational disorder with a refined site occupancy factor of 0.562 (3):0.438 (3)

Short contacts of the sulphur atoms of a 1,2,3,5-dithiadiazolyl dimer with triphenylstibine: first cocrystal with an aromatic compound

Sherpa Romeo yellow journal. Gold open access article. Creative Commons Attribution 3.0 Unported License (CC BY 3.0) appliesThe structure of dimeric 2,7-bisij4-(trifluoromethyl)phenyl]-4λ4,5λ4,9λ4,10λ4-tetrathietoij1,2-a:3,4-a′]bis [1,2,3,5]dithiadiazole (C8H4F3N2S2)2 and its adduct with triphenylstibin (C8H4F3N2S2)2·C18H15Sb, both have triclinic (P¯1) symmetry. They crystallize in layers containing centrosymmetric clusters consisting of four dithiadiazolyl dimers in the parent compound and two such dimers paired with two triphenylstibine units in the aromatic co-crystal. In the co-crystal, the Ph3Sb molecules associate with an equivalent moiety from a neighbouring cluster in a geometry that is very reminiscent of other Ph3Sb-containing structures. Thus, the adduct combines structural elements from those of its component parts. Key interactions between molecules in the pure dithiadiazolyl (S to S) and the co-crystal (S to C) are significantly shorter than the sums of atom van der Waals radii.Ye
