We report the coordination studies of porphyrins with pre-organized but yet flexible straps, each bearing over the
center of the porphyrin either a 2,2-malonic acid diethyl ester residue or a 2,2-malonic acid residue. The straps are
attached to the porphyrin via two adjacent meso positions, 5,10 and 15,20, respectively, and the 2,2-malonic acid
diethyl ester groups are connected to the straps on benzylic carbon atoms. These two structural features allow a
significant flexibility of the straps, as confirmed by the comparison of the X-ray structures of the zinc, nickel, and
lead complexes of porphyrin <b>1</b>. In the latter, the influence of the lone-electron pair of lead is clearly demonstrated.
The coordination of bismuth is also reported.
