چکیده
In the crystal structure of the title compound, C(14)H(16)N(4)O(2) (2+)·2Cl(-)·CH(3)CN, weak inter-molecular N-H⋯Cl hydrogen bonds are found between the H atoms bound to the pyridine and amine N atoms and the chloride anions. The asymmetric unit consits of one half cationic mol-ecule which is located on a centre of inversion, one chloride anion in a general position and one half acetonitrile mol-ecule which is located on a twofold axis. Because of symmetry, the C-H hydrogens of the acetonitrile solvent mol-ecule are disordered over two orientations.

The Zn atom in the title acetonitrile solvate, [Zn(C(34)H(42)N(4)O(2))(C(2)H(6)OS)]·CH(3)CN, exists in a distorted square-pyramidal geometry with the basal plane defined by the N(2)O(2) atoms of the tetra-dentate Schiff base and with the dimethyl sulfoxide O atom in the apical position. The tetra-dentate mode of coordination of the Schiff base ligand leads to a five-membered ZnN(2)C(2) chelate ...

In the title compound, [Cu(C(20)H(10)Br(4)N(2)O(2))(C(3)H(7)NO)]·C(3)H(7)NO, the Cu(II) ion is coordinated by two N atoms and two O atoms from a tetra-dentate Schiff base ligand and the O atom of one dimethyl-formamide ligand in an almost square-pyramidal geometry. The uncoordinated dimethyl-formamide solvent mol-ecule is disordered over two sets of positions with occupancies of 0.741 (4) and 0...

In the title compound, [Cu(C(14)H(12)N(2)O(4))(C(36)H(28)OP(2))]PF(6)·CH(3)CN, the Cu(I) ion is coordinated by two N atoms from the dimethyl 2,2'-biphenyl-4,4'-dicarboxyl-ate ligand and two P atoms from the bis-[2-(diphenyl-phosphino)phen-yl] ether ligand in a distorted tetra-hedral environment. In the cation, the short distance of 3.870 (4) Å between the centroids of the benzene and phenyl rin...
متن کاملHPLC analysis of aliphatic sulfonate surfactants using ion-pair detection.
A method was developed for the analysis of a number of surfactants which contained no UV-chromophores, using RP-HPLC with Indirect Photometric Detection, IPD. Pyridinium salts such as N-methylpyridinium iodide, N-methyl-2,2'-dipyridinium iodide and N,N'-dimethyl-2,2'-dipyridinium diiodide, were used as the visualization reagents, forming ion-pair complexes with the sulfonate surfactants. This a...
