Supramolecular Isomerism, Framework Flexibility, Unsaturated Metal Center, and Porous Property of Ag(I)/Cu(I) 3,3‘,5,5‘-Tetrametyl-4,4‘-Bipyrazolate
Abstract
Template-controlled reactions of 3,3',5,5'-tetramethyl-4,4'-bipyrazole (H2bpz) with [Ag(NH3)2]+ or [Cu(NH3)2]+ give binary metal bipyrazolates [M2(bpz)] (M = Ag, Cu) as two supramolecular isomers (1 and 2). Isomer 1 possesses four-fold interpenetrated (10,3)-a coordination networks, two-fold interpenetrated (10,3)-a channel networks, and guest-accessible coordinatively unsaturated metal clusters. Isomer 2 possesses eight-fold interpenetrated (6(2) x 10)(6 x 10(2)) coordination networks and isolated, small pores. These metal bipyrazolates are chemically stable and thermally stable up to 300-500 degrees C. Their exceptional framework flexibilities have been demonstrated by adsorption measurements and single-crystal diffraction analyses. The guest-accessible Ag(I)/Cu(I) UMC clusters have also been demonstrated to facilitate the accommodation of unsaturated hydrocarbons such as benzene, toluene, mesitylene, and acetylene via weak metal...pi interactions.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
