%X An infinite Ag(I) coordination 41-helical chain, [Ag(Hdpma)](NO3)2·H2O (1), was synthesized
by the self-assembly of AgNO3 and di(3-pyridylmethyl)amine
(dpma). Helix 1 is 5-fold interweaved and has a topological
diamondoid-like net that is extended by ligand-unsupported helix-to-helix
argentophilic interactions. Two identical diamondoid-like nets with
opposite chiralities interpenetrate to form the whole 3D framework
as a meso compound. Typical anion-exchange reactions cause a remarkable
single-crystal-to-single-crystal (SCSC) structural transformation
from the 1D helix 1 to the 0D molecular loop [Ag(dpma-NO)(NO2)]2 (2) (induced by the nitrite anion,
NO2–) and a 1D molecular ladder [Ag(dpma)(H2O)](NO3) (induced by the fluoride anion,
F–). Molecular loop 2 is an N-nitroso compound. This work is the first to present observations
of nitrite-dominated in situ N-nitrosation of an
amine ligand which accompanies SCSC structural transformation via
an anion-exchange reaction.
