Abstract
The title compound, [Ag(C

NO

)]
n
, is a polymeric silver(I) complex of
l
-tyrosine. The Ag
I
atom is connected to N and O atoms of two different
l
-tyrosine ligands in an almost linear arrangement, with an N
i
—Ag—O1 bond angle of 173.4 (2)° [symmetry code: (i)
x
+ 1,
y
,
z
]. The Ag—N
i
and Ag—O bond lengths are 2.156 (5) and 2.162 (4) Å, respectively. The polymeric chains extend along the crystallographic
a
axis. Strong hydrogen bonds of the N—H⋯O and O—H⋯O types and additional C—H⋯O interactions connect these chains into a double-layer polymeric network in the
ab
plane.
