Abstract
Self-assembly of NiX2 (X− = Br− and Cl−) with bidentate dialkyl(3-pyridyl)silane ligands (dialkyl- = (3,3,3-trifluoropropyl)methyl- (L1), = cyclohexylmethyl- (L2), = ethylmethyl- (L3)) gives rise to stable crystals consisting of the Ni3L6 cage motif. Each cage exists as a discrete species encapsulating two halide anions, but its packing mode determines its guest-accessible void volume. The void volume acts as a sustainable reservoir for reversible adsorption/desorption of water in the capacity order Br2@[Ni3L26(H2O)6]Br4·38H2O > Br2@[Ni3L16(H2O)6]Br4·34H2O > Br2@[Ni3L36(H2O)6]Br4·13H2O > Cl2@[Ni3L36Cl3(H2O)3]Cl·5C4H8O.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
