COMMUNICATIONSprovided evidence for the existence of such order also in the solution state.[''] We foresee applications of precision self-asof ever increasing complexity from systems of components of advanced synthetic and informational sophistication. Efforts on using all 5725 reflections. Hydrogen atoms were placed in calculated positions on the appropriate N atoms and on the first four C atoms of the alkyl chain.All non-hydrogen atoms were refined anisotropically and hydrogen atoms were refined by using a riding model (C-H = 0.97. N-H = 0.86 A) with U,,,(H) = 1 .2UEq(C, N). Full-matrix least squares refinement of247 parameters gave R, = 0.1701 [R, = 0.1523 on 1>2a(l)data] and S =1.723. Although the sembly to the targeted fabrication of organized states of matter our part are now being directed towards the inclathration of complementary species in the channel voids of 3,, as well as the elaboration of the periphery for the exploitation of this effective means of generating hexagonal order.[1] a) M.

pounds 3Ϫ5 which range from colourless to orange in appearance. The compositions of these complexes were determined by FAB mass spectrometry (FAB ϭ fast-atom bombardment). The FAB-MS spectrum of complex [Zn 8 O 2 L 2B 6 ] (3) exhibits the correct molecular peak and isotopic pattern at m/z 2519 (Figure 1). According to their FAB-MS data, the corresponding cadmium (4) and manganese (5) complexes have the same composition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
