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

The coordination polymer crystallizes in a monoclinic system of the space group C2/c with a=2.983 1(5) nm, b=1.527 4(3) nm, c= 1.725 3(4) nm, β=107.68(2)°, V=7.490(3) nm3, Z=8, D c=1.382 g/cm3, F(000)=3 260, R=0.059 3, wR 2=0.132 3, S=0.885. The one-dimensional zigzag chain extents through Cu—CN—Fe—CN—Cu linkages. The adjacent two polymer chains are linked by the O—H……NC hydrogen bonding between [CuL(H 2O) 2] 2+ and [Fe(CN) 6] 3- ions to form hydrophilic channels in which water molecules are included.展开更多

The copper complex with the acid [CuL(H 2O)] was obtained in aquo solution and its crystal structure was determined by X ray diffraction with a final R 1 value of 0.024 4 and a wR 2 value of 0.066 0. The crystal is of monoclinic system with a space group P2 1/C . The unit cell parameters are as follows: a =1.218 3(2) nm, b =0.868 31(10) nm, c= 0.979 40 nm , β =96.100(10)°, V =1.032 2(2) nm 3, Z =4, D c=1.862 g/cm 3, F (000)=588, μ =2.129 mm -1 . In crystal, each copper ion is coordinated with three oxygen atoms and one nitrogen atom from H 2L and an oxygen atom from water; the coordination polyhedron around Cu 2+ is a distorted tetragonal pyramid. Cu 2+ are linked by anti anti carboxyl bridges to form endless zigzag chain, a two dimensional network is obtained through the hydrogen bonds between the adjacent chains.展开更多
