Usage

General Description

Lead cyanamidate is a chemical compound that contains lead and cyanamidate ions. It is a white, crystalline solid that is insoluble in water. Lead cyanamidate has several industrial applications, including as a catalyst in organic synthesis and as a pigment in ceramics and glass. However, it is important to note that lead compounds are toxic to human health and the environment, and exposure should be minimized. Therefore, proper handling and disposal procedures are necessary when working with lead compound-containing substances such as lead cyanamidate.

Metathetic synthesis of lead cyanamide as a p-type semiconductor

Lead cyanamide PbNCN was synthesized by solid-state metathesis between PbCl2 and Na2NCN in a 1?:?1 molar ratio, and its structure was confirmed from Rietveldrefinement of X-ray data. Electronic-structure calculations of HSE06 density-functional type revealPbNCN to be an indirect semiconductor with a band gap of 2.4 eV, in remarkable quantitative agreement with the measured value. Mott-Schottky experiments demonstrate PbNCN to be a p-type semiconductor with a flat-band potential of 2.3 eV vs. the reversible hydrogen electrode (RHE) which is commonly used to estimate the value of the valence band edge position. Moreover, thin films of powderous PbNCN were assembled into a photoelectrode for photoelectrochemical water splitting. On the example of p-type PbNCN, this study provides the first experimental evidence that MNCN compounds can be applied as photocathodes for reductive reactions in photoelectrochemical cells.

High-Pressure Behavior of Lead Cyanamide PbNCN

The high-pressure behavior of lead cyanamide, PbNCN, was studied using the diamond anvil cell technique and in situ X-ray powder diffraction at room temperature. By employing a third-order Birch–Murnaghan equation of state, a zero-pressure bulk modulus of K0 = 19(2) GPa was determined, characterizing PbNCN as a very soft material. Additionally, the first linear compression moduli for the inorganic cyanamide were determined to be Ka0 = 145(7) GPa, Kb0 = 37.7(7) GPa, and Kc0 = 15.5(2) GPa. DFT total-energy calculations targeting on the Pb2+ coordination indicate a transition from a typical compression behavior of a two-dimensional layered structure to a more complex one, which was furthermore analyzed by chemical-bonding analysis. Instead of a changing shape of the soft cyanamide unit, we observe an unexpected flattening of the corrugated double layers.
