The title compound, {[Cu(NO(3))(C(2)H(4)N(2))(C(10)H(8)N(2)S(2))(H(2)O)]NO(3).H(2)O}(n), is composed of a one-dimensional linear coordination polymer involving cis-protected copper(II) ions and a 4,4'-dithiodipyridine bridging ligand. The polymeric chains run along the c-axis direction. N-H...O and O-H...O hydrogen bonds involving the coordinating amine(More)
Discrete interlocked three-dimensional structures are synthetic targets that are sometimes difficult to obtain with "classical" synthetic approaches, and dynamic covalent chemistry has been shown to be a useful method to form such interlocked structures as thermodynamically stable products. Although interlocked and defined hollow structures are found in(More)
The complexation of carboxylic acid Monensin A (MonH, 1a) with CoCl2.6H2O and MnCl2.4H2O leads to the formation of mononuclear complexes [Co(Mon)2(H2O)2], 2a and [Mn(Mon)2(H2O)2], 2b, respectively. The unique crystal structures of 2a and 2b were determined by X-ray crystallography. The complexes crystallize in the monoclinic space group P2 1 with an(More)
Cage compounds are fascinating molecules for several reasons. They are defined molecular reaction vessels for “uncommon” products, or used to stabilize highly reactive species in their interior. Recently, materials made from purely organic cage compounds showed remarkable permanent porosities, with very high surface areas and good gassorption properties,(More)
The reaction of 2,2'-dilithiobiphenyl, generated from 2,2'-dibromobiphenyl and n-BuLi, with BCl(3) using n-hexane as solvent provides a high-yielding, simple preparative route to 9-chloro-9-borafluorene 1a. This in turn can be reacted with trimethylsilyl azide to yield 9-azido-9-borafluorene 2. Compound 2 exists as a cyclic trimer in the solid state, but in(More)
Reaction of cadmium perchlorate and the prototypical linear bridging ligand 4,4’-bipyridine (4,4’-bipy) in an ethanol/water mixture affords the one-dimensional coordination polymer, [{Cd(μ-4,4’-bipy)(4,4’-bipy)2(H2O)2}(ClO4)2 ⋅ 2 4,4’-bipy ⋅ 4.5 H2O]n (1). The Cd ions adopt an octahedral coordination sphere and are joined into linear chains by 4,4’-bipy via(More)
Recently, porous organic cage crystals have become a real alternative to extended framework materials with high specific surface areas in the desolvated state. Although major progress in this area has been made, the resulting porous compounds are restricted to the microporous regime, owing to the relatively small molecular sizes of the cages, or the(More)
