η2-SO2 Linkage Photoisomer of an Osmium Coordination Complex

We report the discovery of an η2-SO2 linkage photoisomer in the osmium pentaammine coordination complex, [Os(NH3)5(SO2)][Os(NH3)5(HSO3)]Cl4 (1). Its dark- and light-induced crystal structures are determined via synchrotron X-ray crystallography, at 100 K, where the...

Molecular Structure of Canonical Liquid Crystal Interfaces

Reprinted with permission from J. Am. Chem. Soc., 2017, 139, pp 3841-3850. Copyright 2017 American Chemical Society.Numerous applications of liquid crystals rely on control of molecular orientation at an interface. However, little is known about the precise molecular...

Imparting amphiphobicity on Metal-Organic Framework Materials

The resultant MOFs exhibit both superhydrophobicity and oleophobicity, while retaining high crystallinity and intact porosity Single-crystalline Metal-Organic Framework (MOF) materials show great promise for practical applications and have been extensively...

Basing Earth-abundant metal catalysts at Metal-Organic frameworks

Structural model of homogeneous Zr6O4(OCoCl)4(McO)12 cluster Abstract: Earth-abundant metal catalysts are critically needed for sustainable chemical synthesis. Here we report a simple, cheap and effective strategy of producing novel earth-abundant metal catalysts at...

Surprising Ground State Structure of Crystalline Layered Nickelate

Crystal structure of La-438 The quasi-2D nickelate La4Ni3O8 (La-438), consisting of trilayer networks of square planar Ni ions, is a member of the so-called T′ family, which is derived from the Ruddlesden–Popper (R-P) parent compound La4Ni3O10−x by removing two oxygen...
