摘要:In the title Schiff base complex, [Ni(C27H24N2O2)], the NiII atom shows a slightly distorted square-planar geometry. The dihedral angle between the mean planes of the two aromatic rings is 6.16 (6)°. In the crystal, pairs of intermolecular weak C—H...O hydrogen bonds link ne...

摘要:The asymmetric unit of the title compound, [Co(C23H28N2O4)(C9H9O3)]·C2H5OH·H2O, comprises one complex molecule, a water molecule of crystallization and an ethanol molecule of crystallization, which is disordered over two positions with a ratio of refined site occupancies of ...

摘要:We present a variance shift model for a linear measurement error model using the corrected likelihood of Nakamura (1990). This model assumes that a single outlier arises from an observation with inflated variance. The corrected likelihood ratio and the score test statistics are p...

摘要:The title complex, [Cd2(NO3)4(C24H16N6)(CH4O)2], displays a centrosymmetric dinuclear structure, in which the 2,3,5,6-tetra-2-pyridinylpyrazine (tppz) ligand links two Cd ions separated by 7.323 (4) Å. Each CdII center is seven-coordinated by three N-atom donors of tppz in o...
