Abstract

Reversible adsorption of gases distinguishes the coordination polymers {[M2(4,4′-bpy)3(NO3)4](H2O)x}n (M = Co., x = 4; M = Ni, x = 4; M = Zn, x = 2), which are formed from M(NO3)2 and 4,4′-bipyridine in acetone/ethanol. The channeling cavities in the crystal frameworks (shown schematically on the right) have dimensions of about 3 × 6 Å along the a axis and about 3 × 3 Å along the b axis, and reversibly adsorb CH4, N2, and O2 in the pressure range of 1–36 atm without deformation of the crystal framework.

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.
