Our paper on SBUs for MOFs is among the top 10 most accessed in Chem. Rev. Soc. during 2009.

2010/01/10: "Chem Soc Rev Top 10 2009, (12 January 2010) In 2009 we published more reviews than ever before but find out below which were the most accessed online." Link  [ABSTRACT] This critical review presents a comprehensive study of transition-metal carboxylate clusters which may serve as secondary building units (SBUs) towards construction and synthesis of metal–organic frameworks (MOFs). We describe the geometries of 131 SBUs, their connectivity and composition. This contribution presents a comprehensive list of the wide variety of transition-metal carboxylate clusters which may serve as secondary building units (SBUs) in the construction and synthesis of metal–organic frameworks. The SBUs discussed here were obtained from a search of molecules and extended structures archived in the Cambridge Structure Database (CSD, version 5.28, January 2007) which included only crystals containing metalcarboxylate linkages (241 references). Link
