Reconstructive Transitions from Rotations of Rigid Heteroanionic Polyhedra.

Journal of the American Chemical Society

Holland M, Charles N, Rondinelli JM, Poeppelmeier KR.
PMID: 27532822
J Am Chem Soc. 2016 Sep 14;138(36):11882-9. doi: 10.1021/jacs.6b06813. Epub 2016 Aug 30.

Phase transitions are ubiquitous in structurally complex transition metal compounds composed of homoanionic polyhedra, including nitrides, oxides, and fluorides. The symmetry breaking that occurs across polymorphic transitions is often achieved by small atomic displacements, rendering these displacive transitions reversible....

Organometallics. 2015 Oct 12;34(19):4775-4780. doi: 10.1021/acs.organomet.5b00631. Epub 2015 Aug 20.

A thorough investigation of the challenging Pd-catalyzed fluorination of five-membered heteroaryl bromides is presented. Crystallographic studies and density functional theory (DFT) calculations suggest that the challenging step of this transformation is C-F reductive elimination of five-membered heteroaryl fluorides from...

From Minor Side Phases to Bulk Samples of Lanthanum Oxonitridosilicates: An Investigation with Microfocused Synchrotron Radiation.

Inorganic chemistry

Inorg Chem. 2016 Apr 04;55(7):3624-9. doi: 10.1021/acs.inorgchem.6b00143. Epub 2016 Mar 15.

Microcrystals of the oxonitridosilicate oxide La(11)Si(13)N(27.636)O(1.046):Ce(3+) were obtained by exploratory high-temperature synthesis starting from La, La(NH2)3, Si(NH)2, BaH2, and CeF3. Owing to the small size of the crystals, microfocused synchrotron radiation was used for structure investigations (space group Cmc21...
