A hardwon dirhodium paddlewheel with guanidinate type (hpp) bridging ligands.
We report a dirhodium paddlewheel compound which has an Rh2(5+) core enveloped by four guanidinate ligands and an axially coordinated bromine atom; Rh2(hpp)4Br crystallizes as a 1-D chain with a Rh-Rh distance of 2.430(3) è and a Rh-Rh bond order of 1.5 (hpp = the anion of 1,3,4,6,7,8-hexahydro-2H-pyrimido[1,2a]pyrimidine).
متن کاملA novel heteroleptic paddlewheel diruthenium bicyclic guanidinate complex: synthesis, structure, and scope.
A novel paddlewheel or 'lantern' heteroleptic diruthenium guanidinate complex Ru(2)(TBO)(2)(OAc)(2)Cl x 3MeCN (1 x 3MeCN) was synthesized and structurally characterized. Compared with a known tetra-substituted di-ruthenium guanidinate complex Ru(2)(TBD)(4)Cl, 1 revealed structural dissimilarities with internal twisting.

A 3x3x3 nm cubic coordination compound quantitatively self-assembled from 6 palladium ions and 12 bent ligands with a 90 degrees bend angle.
متن کاملMolecular coordination of hierarchical self-assembly
A serious challenge to nanotechnology is the problem of assembling complex physical systems that are structured from the nanoscale up through the macroscale, but embryological morphogenesis provides a good model of how it can be accomplished. Morphogenesis (whether natural or artificial) is an example of embodied computation, which exploits physical processes for computational ends, or performs...
متن کاملSelf-assembly of heteroleptic dinuclear metallosupramolecular kites from multivalent ligands via social self-sorting
A Tröger's base-derived racemic bis(1,10-phenanthroline) ligand (rac)-1 and a bis(2,2'-bipyridine) ligand with a central 1,3-diethynylbenzene unit 2 were synthesized. Each of these ligands acts as a multivalent entity for the binding of two copper(I) ions. Upon coordination to the metal ions these two ligands undergo selective self-assembly into heteroleptic dinuclear metallosupramolecular kite...
