Template effect versus hydogen bonding in self‐assembly: As predicted, the scaffold of molecular gyroscope [(NaBr) 2 ∩Cu 6 {(2,5‐Me 2 C 6 H 3 CH 2 )N(CH 2 CH 2 O) 2 } 6 ] ( 1 ) is generated from N‐substituted diethanolamine together with a copper( II ) salt and sodium bromide. However, we did not predict the one‐dimensional coordination polymer $\rm{^{1}_{\infty }}$ [Cu 4 {H[HN(CH 2 CH 2 O) 2 ]} 4 (OAc) 4 ] ( 2 ) generated with an unsubstituted diethanolamine. The formation of 2 is a further impressive example of nature's virtuosity in using hydrogen bonds.
