The air compressor provides not only the required pressure air for the cooling equipment and refrigeration plant, but also the raw material required for the air separation plant. Utilizing the air compressor is extremely extensive in many significant departments such as the metallurgy, oil and chemical industry. The air compressor production process is a… (More)
In the title heterodinuclear complex, [CuNa(C(8)H(7)O(3))(2)(NO(3))](n), the Cu(II) ion is five-coordinated in a square-pyramidal arrangement by four atoms of two different ligand molecules in equatorial positions and one remote nitrate O atom in the apical position. The Na(+) ion is eight-coordinated by four ligand O atoms and four nitrate O atoms. The… (More)
In the mononuclear salen-type complex, [Er(NO(3))(3)(C(18)H(20)N(2)O(4))], the Er(III) ion is ten-coordinated in a distorted hexa-deca-hedral geometry by six O atoms of three nitrate anions and four O atoms of the salen-like ligand. Inter-molecular N-H⋯O hydrogen bonds occur. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.
In the title mononuclear Schiff base complex, [Dy(NO(3))(3)(C(18)H(20)N(2)O(4))], the Dy(III) ion is ten-coordinated in a distorted hexa-deca-hedral geometry by six O atoms of three nitrate anions and four O atoms of the Schiff base ligand. An intra-molecular N-H⋯O hydrogen bond occurs. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen… (More)
In the title complex, [CuSm(C(19)H(20)N(2)O(4))(NO(3))(3)]·CH(3)CO-CH(3), the Cu(II) atom is four-coordinated in a square-planar geometry by two O atoms and two N atoms of the deprotonated Schiff base. The Sm(III) atom is ten-coordinate, chelated by three nitrate groups and linked to the four O atoms of the deprotonated Schiff base.
