A Cu‐Based Near‐IR Active MOF with an Ion‐Pair Guest Exhibiting Versatile and Selective Gas‐Solid Reactivity

Advanced Materials, EarlyView.
The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.

Tetrakis(μ2-2,2-dimethylpropanoato-κ2O,O′)bis[(pyridine-κN)copper(II)]: a monoclinic polymorph

Acta Crystallographica Section E, 2010
The structure of the dinuclear title complex, [Cu2(C5H9O2)4(C5H5N)2], represents a monoclinic polymorph of the previously reported triclinic form [Blewett et al. (2006). Acta Cryst. E62, m420–m422].

The monoclinic phase of PZT ceramics: Raman and phenomenological theory studies

, 1999
This work reports on the first Raman detection of the tetragonal to monoclinic phase transition in PZT ceramics near morphotropic phase boundary at low temperatures.

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing

Advanced Materials, EarlyView.
Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

N′-Benzoyl-N,N-diethylthiourea: a monoclinic polymorph

Acta Crystallographica Section E, 2010
In the crystal of the title compound, C12H16N2OS, inversion dimers linked by pairs of N—H...S hydrogen bonds occur, generating R22(8) loops. The molecules are also linked by weak C—H...O hydrogen bonds.

One‐Dimensional Materials Supported in Two‐Dimensional Van der Waals Metal–Organic Frameworks with Optical Anisotropy Switching via Twist‐Engineering

Advanced Materials, EarlyView.
We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Monoclinic modification of di-n-butyldichlorido(1,10-phenanthroline-κ2N,N′)tin(IV)

Acta Crystallographica Section E, 2010
The Sn(IV) atom in the title compound, [Sn(C4H9)2Cl2(C12H8N2)], is chelated by the N-heterocycle; the n-butyl groups are trans to each other whereas the Cl atoms are cis to each other.

Crystal structure stability and electronic properties of layered nickelate La$_4$Ni$_3$O$_{10}$

, 2017
We investigate the crystal structure and the electronic properties of the trilayer nickelate La$_4$Ni$_3$O$_{10}$ by means of quantum mechanical calculations in the framework of the density functional theory. We find that, at low temperature, La$_4$Ni$_3$

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions

Advanced Materials, EarlyView.
ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.
