The L1 ligand adopts planar configuration, whereas the naphthyridine imidazole rings deviate from planarity in L2 yielding a polymeric structure.
These three pairs, and the corresponding bonds, adopt a planar triangular arrangement, and the H−C−H and H−C=C angles are predicted to be close to 120°, as is found experimentally.
All the complexes adopt square planar geometry.
The metal chelates adopt square planar geometrical arrangements around the metal ions.
The spectral and analytical data reveal that the complexes adopt square planar geometry.
This is the only known example of a two atom-bridged 1,3,5-triphenylbenzene derivative to adopt a planar structure.
The molecular chains in it adopt the planar zigzag conformation, which was only found in the sample under tension.
In contrast, since the polymer backbones adopt fully planar conformations in form I and II modifications, comparisons between them allow us to focus on interchain interactions.
We adopt the planar circular restricted three-body problem (PCR3BP) as the spacecraft model, and reduce computation of optimal transfers to a nonlinear boundary value problem (BVP).
Since the polythiophene backbones and alkyl chains adopt fully planar and all-trans conformations, respectively, at room temperature [25, 26], the stability of a packing structure is determined by nonbonded attractions between polymer backbones and between alkyl chains [27 29].
Since the polymer backbones adopt fully planar conformations in both form I and II modifications, the differences in PL properties between them can be attributed to the difference in the stacking distance.
