Figure 3.
Superposition of 16 trimeric N@d layers of known structure,
including 3 exemplars from this study as listed in Table S1, all
coordinating chloride. In 6 cases the polar network is extended
by Thr in e of the neighboring chain and in 7 cases by Asn or
Asp in g of the same chain, all with the same geometry as in
SadAK3, including the bridging water molecule. Dimeric,
tetrameric, and 2 further trimeric instances are shown in Fig.
S2.
