چکیده
Reactions between Co(NCS)2 and 24,24-[2,5-bis(cyclohexyloxy)-1,4-phenylene]di(13,22 : 26,33-terpyridine) (1), 24,24-[2,5-bis(cyclohexylmethoxy)-1,4-phenylene]di(13,22 (2), 24,24-[2,5-bis(2-phenylethoxy)-1,4-phenylene]di(13,22 (3) under conditions of crystal growth by layering at room temperature lead to 3-dimensional nets with either a cds or trinodal self-penetrating topology depending upon the solvents (MeOH/C6H5Cl, MeOH/1,2-Cl2C6H5, MeOH/CHCl3) used in crystallization experiments. The network was found for [Co(NCS)2(1)]n⋅2nC6H4Cl2, [Co(NCS)2(2)]n⋅4nC6H4Cl2, [Co(NCS)2(3)]n⋅2.5nC6H5Cl, while net observed [Co2(NCS)4(2)2]n⋅5.5nCHCl3⋅0.2nMeOH. Preliminary structural data single crystals from reactions 1 3 MeOH/CHCl3 solvent combinations also evidenced assemblies nets. Both topologies assemble combination planar, 4-connecting metal ligand nodes. role directing type is investigated.

The asc trinodal platform: two-step assembly of triangular, tetrahedral, and trigonal-prismatic molecular building blocks.
Metal–organic materials (MOMs) assembled from metalbased or organic molecular building blocks (MBBs) and organic linkers have attracted increasing scientific interest during the past decade. Their structure (especially their modularity) and properties (especially extra-large surface area) have made them an attractive class of porous materials for applications including gas purification and stor...
متن کاملThe Difference All-Difference Makes
We perform a comprehensive theoretical and experimental analysis of the use of all-different constraints. We prove that generalized arc-consistency on such constraints lies between neighborhood inverse consistency and, under a simple restriction, path inverse consistency on the binary representation of the problem. By generalizing the arguments of Kondrak and van Beek, we prove that a search al...
متن کاملRewiring makes the difference
While canonical pathways and regulatory networks provide a representation of molecular interactions in the cell that appears static and immutable, actual regulatory pathways are anything but. Rather, they appear to reconfigure dynamically as a function of the specific molecular context in which they operate. This was shown initially in yeast (Luscombe et al, 2004) and more recently in mammalian...
متن کاملRace: The Difference That Makes a Difference
During the last two decades, critical enquiry into the nature of race has begun to enter the philosophical mainstream. The same period has also witnessed the emergence of an increasingly visible discourse about the nature of information within a diverse range of popular and academic settings. What is yet to emerge, however, is engagement at the interface of the two disciplines – critical race t...
متن کاملSimulation Using Building Blocks
In this paper we sketch how the use of building blocks provides added value for improving the effectiveness of simulation studies. Research conducted by other groups regarding building blocks is in our view not yet sufficient for successful application in the field of discrete event simulation. In addition the sets of building blocks provided by simulation vendors do not provide the added value...
