β-Li₂Zn₅: A Low Symmetric Polar Intermetallic Compound

Inorganic Chemistry, 2019
The crystal structure of the high-temperature modification of the compound Li2Zn5 was determined using single-crystal X-ray diffraction data. It is the first representative of a new binary structure type with triclinic space group P1̅, where the parameters of the unit cell are a = 8.0073(3)Å, b = 11.5956(6)Å, c = 15.2956(5)Å, α = 96.39°, β = 101.92 ...

Electrocrystallization: A Synthetic Method for Intermetallic Phases with Polar Metal–Metal Bonding

Inorganic Chemistry, 2016
Isothermal electrolysis is a convenient preparation technique for a large number of intermetallic phases. A solution of the salt of a less-noble metal is electrolyzed on a cathode consisting of a liquid metal or intermetallic system. This yields crystalline products at mild reaction conditions in a few hours.

Electronic and optical properties of polar intermetallic compound BaSn3: First principles study

Optik, 2020
Abstract The electronic and optical properties of intermetallic compound BaSn3 are investigated at high pressure from the first principles density functional theory calculations using the plane-wave pseudo-potential method within generalized gradient approximations in the forms of PBEsol (PBEsol-GGA).

Yb3CoSn6 and Yb4Mn2Sn5: New polar intermetallics with 3D open-framework structures

Journal of Solid State Chemistry, 2008
Abstract Two new ternary ytterbium transition metal stannides, namely, Yb3CoSn6 and Yb4Mn2Sn5, have been obtained by solid-state reactions of the corresponding pure elements in welded tantalum tubes at high temperature. Their crystal structures have been established by single-crystal X-ray diffraction studies.

Polarized evolution of interfacial intermetallic compounds (IMCs) in interconnects under electromigration (EM)

Journal of Materials Science: Materials in Electronics, 2017
In situ observation of electromigration (EM) has been carried out on cross-sectioned copper/tin–copper/copper (Cu/Sn0.7Cu/Cu) line-type interconnects. The surface vertical variation after EM is measured by step profiler, which indicates serious mass migration during EM. The EM rate is calculated using two distinct methods, in situ mark movement and the

ChemInform Abstract: Remarkably Diverse Interstitial Chemistry of the Polar Intermetallic Phase Zr5Sb3.

ChemInform, 1988
AbstractIt is demonstrated that the hexagonal title phase exhibits a rich interstitial chemistry in which at least 18 different elements Z (C, O, Al, Si, P, S, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Ru, Ag, Sb) with a wide variety of normal valence requirements can be bonded in the center of octahedral Zr6Sb6 units.
