Abstract

Five new coordination compounds with 4,4‘-azopyridine (azpy), [Mn(azpy)(NO 3 ) 2 (H 2 O) 2 ]·2EtOH ( 1 ·2EtOH), [Co 2 (azpy) 3 (NO 3 ) 4 ]·Me 2 CO·3H 2 O ( 2 ·Me 2 CO·3H 2 O), [Co(azpy) 2 (NCS) 2 ]·0.5EtOH ( 3 ·0.5EtOH), [Cd(azpy) 2 (NO 3 ) 2 ]·(azpy) ( 4 ·azpy), and [Cd 2 (azpy) 3 (NO 3 ) 4 ]·2Me 2 CO ( 5 ·2Me 2 CO), have been synthesized and structurally characterized. The reaction of Mn(NO 3 ) 2 ·6H 2 O with azpy in ethanol/acetone affords 1 ·2EtOH, whose network consists of one-dimensional chains of [Mn(azpy)(H 2 O) 2 ] n . The chains are associated by hydrogen bonding to provide a logcabin -type three-dimensional structure, which creates about 8 × 8 Å of channels, filled with ethanol molecules. The treatment of Co(NO 3 ) 2 ·6H 2 O and Co(NCS) 2 ·4H 2 O with azpy produces 2 ·Me 2 CO·3H 2 O and 3 ·0.5EtOH, respectively, which have a brick - wall and a rhombus -type two-dimensional networks. The reaction of Cd(NO 3 ) 2 ·4H 2 O with azpy affords 4 ·azpy from the ethanol/H 2 O media, while the reaction in the ethanol/acetone media provides 5 ·2Me 2 CO. 4 ·azpy and 5 ·2Me 2 CO form a square - grid- and a herringbone -type two-dimensional networks, respectively. The two-dimensional sheets of 4 ·azpy stack without interpenetration, leading to large size of channels, which are filled with free azpy molecules. The two-dimensional networks of 2 ·Me 2 CO·3H 2 O, 3 ·0.5EtOH, and 5 ·2Me 2 CO are quadruply, doubly, and triply interpenetrated, respectively. Despite the interpenetration, their networks create the microporous channels filled with guest solvent molecules. The dried compounds 2, 3, and 5 adsorb methane between 1 and 36 atm at 25 °C, in which 3 and 5 exhibit Langmuir-type isotherms. The inherent micropore volumes for 3 and 5 are 0.685 and 3.30 mmol/g, respectively. XRPD measurements under reduced pressure at 100 °C reveal that the channel structure of 3 is the most stable in these compounds; the observed XRPD pattern is in good agreement with that of the simulated pattern of the single-crystal model. Compounds 2 and 5 also retain the porous structures, however, their pore structures are distorted upon loss of guest included molecules.

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.
