It was characterized by X ray diffraction. The crystal of the title compound, [Mn(CHZ) 3](ClO 4) 2, belongs to space group P2 1/n with the crystal parameters a=1.019 7(2) nm, b=0.859 3(1) nm, c=2.141 2(3) nm, β=100.86(1)°; V=1.842 6(5) nm3, Z=4. The results show that all carbohydrazides are coordinated as bidentate by the oxygen atom of the carbonyl group and one nitrogen atom of the end group, forming a distorted octahedron. The explosive properties of the title complex were tested, the application in the engineering detonator was investigated.展开更多
