Zinc phosphide (Zn 3 P 2) is an inorganic chemical compound.It is a grey solid, although commercial samples are often dark or even black. It is used as a rodenticide. [5] Zn 3 P 2 is a II-V semiconductor with a direct band gap of 1.5 eV [6] and may have applications in photovoltaic cells. [7]
Because other species of mammals and birds may prey upon affected rodents, or directly ingest rodenticide bait, there is a risk of primary, secondary or tertiary exposure; examples are described in a 2012 publication on veterinary toxicology. [3]
Zinc diphosphide (Zn P 2) is an inorganic chemical compound. It is a red semiconductor solid with a band gap of 2.1 eV . [ 2 ] It is one of the two compounds in the zinc-phosphorus system, the other being zinc phosphide (Zn 3 P 2 ) .
Zinc phosphide is a common ingredient in rat poison or rodenticide. Zinc phosphide is a combination of phosphorus and zinc. If ingested, the acid in a dog's stomach turns the compound into phosphine, which is a toxic gas. The phosphine gas crosses into the dog's cells and causes the cell to die.
Structure of a monomeric zinc dialkyldithiophosphate No fluoro complexes are known, but complexes with the other halides and with pseudohalides , [ZnX 3 ] − and [ZnX 4 ] 2− can be prepared. The case of the thiocyanate complex illustrates the class A character of the zinc ion as it is the N-bonded isomer, [Zn(NCS) 4 ] 2− in contrast to [Cd ...
Zinc phosphate is an inorganic compound with the formula Zn 3 (PO 4) 2. This white powder is widely used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead ).
In the room-temperature form, the zinc atoms are tetrahedrally coordinated and the arsenic atoms are surrounded by six zinc atoms at the vertices of a distorted cube. The crystalline structure of zinc arsenide is very similar to that of cadmium arsenide (Cd 3 As 2), zinc phosphide (Zn 3 P 2) and cadmium phosphide (Cd 3 P 2).
Zinc cadmium phosphide arsenide (Zn-Cd-P-As) is a quaternary system of group II (IUPAC group 12) and group V (IUPAC group 15) elements. Many of the inorganic compounds in the system are II-V semiconductor materials .
