Regium-π vs Cation-π Interactions in M2 and MCl (M = Cu, Ag and Au) Complexes with Small Aromatic Systems: An ab Initio Study

open access: yesInorganics, 2018
In this study we have theoretically analyzed (RI-MP2/def2-TZVP) the ability of metal moieties involving elements from group IB (Cu, Ag and Au) to establish either regium-π or cation-π interactions with π-systems of different electronic nature ...

Host plant‐specific volatiles of Beauveria bassiana‐colonized plants initiate trophic plant–aphid–predator cascades

open access: yesPest Management Science, EarlyView.
Endophytic colonization of melon plants by B. bassiana modifies the crop volatile profiles in a genotype‐dependent manner. A predator choice is biased toward endophytically colonized plants infested with aphids revealing a guardian within effect of the fungus of great potential in integrated pest management.

Isolation and Structural Elucidation of the Pnictogen Polysulfate Compounds As2[S2O7]2[S3O10] and [SeCl3][Pn(S2O7)2] (Pn = Sb, Bi)

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The isolation and solid‐state structures of the two disulfate‐containing pnictogenates [SeCl3][Pn(S2O7)2] (Pn = Sb, Bi), as well as the mixed‐anionic As2[S2O7]2[S3O10] are presented. The former two consist of complex ∞1{[Pn(S2O7)1/1t(S2O7)2/2e]‐}$$ {\infty }^{1}\left\{{\left[\mathrm{Pn}{\left({\mathrm{S}}_{2}{\mathrm{O}}_{7}\right)}_{1/1}^{\mathrm{t}}{\
