Formation of Interwoven 2‐D Networks by the Spontaneous Strict Self‐Assembly of [{M(CO)3(μ3‐OH)}4] (M Mn, Re) and Complementary Angular Spacer Molecules

The construction of supramolecular structures by simple cocrystallization of compounds whose molecular building blocks are complementary is amazingly easy. Td-symmetric molecules that can function as Hbond donors, for instance [{M(CO)3(μ3OH)}4] (M  MnI, ReI) (shown on the right), and bi- or multifunctional Hbond acceptors such as 1,3-diaminopropane and hexamethylenetetramine form two-dimensional “chickenwire” networks.
