Description
Magnesium nitride has the molecular formula of
Mg3N2 and the molecular weight of 100.9494 g/mol.
It can be prepared by the reaction of Mg metal in
a pure stream of nitrogen gas:
3Mg + 2N2? Mg3N2
At room temperature and pressure, it is a greenish
yellow powder. Its density is 2.712 g/cm3 and it melts
at about 1500 °C. Its CAS number is 12057-71-5. It reacts
with water to produce ammonia gas, as do many metal
nitrides:
Mg3N2 + 6H2O ? 3Mg(OH)2 + 2NH3
In fact, when magnesium is burned in air, some
magnesium nitride is formed in addition to the principal
product, MgO.
Where two Mg2+ ions are directly linked together. The
lattice parameter and coordinates of Mg3N2 were
obtained. It is a cubic anti-bixbyite structure with lattice
parameter a = 9:9528? . The metal (Mg) atoms are in
general positions 48 e of space group Ia3 (x; y; z). There
are two crystallographically different kinds of N atoms:
N1 is in positions 8b (1/4, 1/4, 1/4), and N2 in positions
24d (x, 0,1/4). In this structure, the N-arrays are fairly close
to ideal cubic close packing. The 12 shortest N–N
distances are in the range from 3.31 to 3.72?. Each
nitrogen atom is coordinated by six Mg atoms. N1 has
six Mg neighbors with a distance of 2.14?, while N2 is
coordinated by six Mg with different N–Mg distances
ranging from 2.084 to 2.179?. The Mg–Mg distances are
2.72?.

Uses
The use of magnesium nitride as a convenient source of ammonia allows a direct transformation of esters to primary amides. Methyl, ethyl, isopropyl, and tert-butyl esters are converted to the corresponding carboxamides in good yields.
Check Digit Verification of cas no
The CAS Registry Mumber 12057-71-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,5 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 12057-71:
(7*1)+(6*2)+(5*0)+(4*5)+(3*7)+(2*7)+(1*1)=75
75 % 10 = 5
So 12057-71-5 is a valid CAS Registry Number.
