Packing principles of thioether derivatives of triarylamine silver salts

Tris(4-methylthiophenyl)amine, 1, has been crystallized together with three silver salts, AgOTf (silver trifluoromethane sulfonate), AgClO4, and AgSbF6. The resulting crystal structures have been determined by singlecrystal X-ray methods. All three…

AN ORGANIC-SOLID WITH WIDE CHANNELS BASED ON HYDROGEN-BONDING BETWEEN MACROCYCLES

Research on microporous solids has focused largely on inorganic materials such as aluminosilicates (zeolites), aluminophosphates, pillared clays and other layered materials(1,2). An elusive goal has been the design of new materials with specific…

SPONTANEOUS ASSEMBLY OF A HINGED COORDINATION NETWORK

THE field of supramolecular chemistry has advanced to a stage at which it is possible to select building blocks that will self-assemble into structures with specific network topologies(1-3). This makes possible the rational design and synthesis of…

CRYSTALLIZATION OF 4,4'-BIPHENYLDICARBONITRILE WITH SILVER(I) SALTS - A CHANGE IN TOPOLOGY CONCOMITANT WITH A CHANGE IN COUNTERION LEADING TO A NINEFOLD DIAMONDOID NETWORK

The preparation and X-ray crystal structures of two coordination networks [Ag(BPCN)(CF3SO3)]. C6H6 1 and [Ag(BPCN)(2)]PF6 2 (BPCN = 4,4'-biphenyldicarbonitrile) are described; 1 consists of infinite chains; however, 2 exists as a ninefold…

Exchange properties of the three-dimensional coordination compound 1,3,5-tris(4-ethynylbenzonitrile)benzene center dot AgO3SCF3

Properties such as guest removal and exchange within a host crystal are investigated for benzene . 1,3,5-tris(4-ethynylbenzonitrile)(1). silver triflate(AgOTf) (polymorph A). The 15 Angstrom x 22 Angstrom channels in the crystal structure are…

Coordination networks based on multitopic ligands and silver(I) salts: A study of network connectivity and topology as a function of counterion

We show that much like hgdrog en bonding, Ag-N coordination bonds can be reliably used for the construction of supramolecular networks. From a solid-state structural study of silver(I) complexes of multitopic ligands, we describe coordination…

Silver(I) complexes of 1,4-dicyanobenzene

The crystal structures of the complexes of 1,4-benzenedinitrile with silver(I) trifluoromethanesulfonate, catena-poly[{mu-(aqua-O, O)-bis[(trifluoromethanesulfonato-O)silver(I)]}…
