Crystal structure of (1,10-phenanthroline-N,N')(1,4,7,10-tetraazacyclododecane-N,N',N",N"')nickel(II) diperchlorate.
The crystal structure of the title compound, [Ni(C8H20N4)(C12H8N2)](ClO4)2, has been determined by X-ray diffraction. The Ni(II) ion is six coordinated with four nitrogen atoms of the tetradentate macrocyclic ligand and two nitrogen atoms of the bidentate ligand in a distorted octahedron geometry. The folded tetradentate macrocyclic ligand adopts a configuration having four five-membered chelat...

The title complex salt, [CuCl(C(12)H(8)N(2))(2)][Tb(NO(3))(4)(C(12)H(8)N(2))], consists of discrete [CuCl(phen))(2)](+) cations and [Tb(NO(3))(4)(phen)](-) anions (phen is 1,10-phenanthroline). The [CuCl(phen))(2)](+) cation contains a five-coordinate Cu(2+) ion, ligated by two bidentate phen ligands and one Cl(-) ion, exhibiting a distorted CuN(4)Cl trigonal-bipyramidal geometry. In the [Tb(NO...

In the title complex, [La(2)(C(10)H(10)NO(3))(2)(NO(3))(4)(C(12)H(8)N(2))(4)], each La(III) ion is ten-coordinated by four N atoms from two bidentate 1,10-phenanthroline ligands and by six O atoms, two from the N-acetyl-N-phenyl-glycinate ligands and four from two nitrate anions. Two La(III) cations, which exhibit a distorted bicapped square-anti-prismatic coordination, are bridged by two N-ace...
متن کاملConformational properties of N-acetyl-L-alanine N',N'-dimethylamide.
Ab initio/DFT analysis of the conformational properties of free Ac-Ala-NMe(2) (N-acetyl-L-alanine-N',N'-dimethylamide) in terms of the N-H.O, N-H.N, C-H.O hydrogen bonds and C(delta+) = O(delta-) dipole attractions was performed. The Ala residue combined with the C-terminal tertiary amide prefers an extended conformation and that characteristic of the (i + 1)th position of the betaVIb turn. The...
متن کاملN,N′-Diacetyl-N′-[(4-nitrophenoxy)acetyl]acetohydrazide
The asymmetric unit of the title compound, C(14)H(15)N(3)O(7), contains two independent mol-ecules which are linked into a pseudocentrosymmetric dimer by a π-π inter-action, as shown by the short distance of 3.722 (5) Å between the centroids of the benzene rings. An extensive network of weak inter-molecular C-H⋯O hydrogen bonds helps to stabilize the crystal packing.
