摘要:In contrast to transition elements, s- and p-block metal compounds that coordinate carbon monoxide (CO) under near-ambient conditions are elusive. Here, we report an isolable, crystalline main-group metal carbonyl complex and its isomerization to a carbene-stabilized metal atom. The stannylene (Boryl)2Sn [where Boryl is B(NDippCH)2] coordinates CO reversibly, affording an isolable adduct below 0 degrees C, which was characterized by x-ray crystallography. This complex rearranges at temperature...

摘要:Photosystem I (PSI) is a pigment-protein complex, which converts light energy into chemical energy in photosynthesis. Among photosynthetic organisms, PSI-LHC (light-harvesting complex) structures exhibit substantial differences in their sizes, reflecting adaptation to different light environments. Here we report the structure of a PSI-fucoxanthin chlorophyll a/c binding protein (FCPI) supercomplex from the coccolithophore Emiliania huxleyi (Eh) at 2.79-angstrom resolution by cryo-electron micr...
