FORMATION OF INTERWOVEN 2-D NETWORKS BY THE SPONTANEOUS STRICT SELF-ASSEMBLY OF [(M(CO)3(MU(3)-OH))4](M=MN, RE) AND COMPLEMENTARY ANGULAR SPACER MOLECULES

The construction of supramolecular structures by simple cocrystallizat ion of compounds whose molecular building blocks are complementary is amazingly easy. T(d)-symmetric molecules that can function as H-bond d onors. for instance [{M(CO)3(mu3-OH)}4] (M = Mn(I). Re(I)) (shown on t he right), and bi- or multifunctional H-bond acceptors such as 1.3-dia minopropane and hexamethylene-tetramine form two-dimensional ''chicken -wire'' networks.
