Leaf and crown characteristics were examined for 24 tree and herbaceous species of contrasting architectures from the understory of a lowland rainforest. Light-capture efficiency was estimated for the crowns of the different species with a three-dimensional geometric modeling program. Causal relationships among traits affecting light absorption at two hierarchical levels (leaf and whole crown) ...

Pinus halepensis Mill. is a Mediterranean pioneer forest species with shade intolerance features. The 15 purpose of this study is to better understand how stand fertility and allelopathic properties of adult trees influence 16 shade acclimation of saplings. Crown growth and morphological plasticity were studied under different light, 17 fertilization, and allelopathic conditions in a nursery ex...

The Zn(II) ion in the title compound, [Zn(C(24)H(28)N(2)O(6))](n), is located on a twofold rotation axis and is at the midpoint of a crown-4 moiety of 3,3'-[(1,7-dioxa-4,10-diaza-cyclo-dodecane-4,10-di-yl)bis-(methyl-ene)]dibenzoate anion. It is octahedrally coordinated by two N atoms and two O atoms of the crown moiety from one ligand and two carboxyl-ate O atoms from two bridging intra-chain ...

The asymmetric unit of the title compound, H(3)O(+)·ClO(4) (-)·C(20)H(24)O(6), contains two mol-ecules/ions of each species. Both dibenzo-18-crown-6 mol-ecules have a complexed hydro-nium ion inside their cavity with O-H⋯O and O-H⋯(O,O) links between the two species. The associated perchlorate anions also accept O-H⋯O hydrogen bonds from the hydro-nium ion. Both crown ether mol-ecules are prese...

In the title compound, [K(2)PtCl(4)(C(12)H(24)O(6))(2)], the Pt(II) ion is located on an inversion centre and is coordinated by four Cl atoms, forming a square-planar geometry. The K(I) ion is coordinated by six O atoms of the crown ether and two bridging Cl atoms. The K(I) ion is displaced by 0.756 (2) Å from the mean plane of the six O atoms of the crown ether. The mol-ecules are connected by...
