Crystal Structure of [1-{(2-Oxyphenyl)iminomethyl}benzen- 2-oxy-N,O,O′]cyclopropylamine-Nnickel(II) Complex
(1997)
The structures of monomeric Ni complexes in the
presence of a tridentate ONO or ONS Schiff-base ligand
and different monodentate ligands (piperidinel, pyrrolidine2 and cyclohexylamine3) were reported previously. In those ...
Crystal Structure of (N,N′-Disalicylidene-2,3-diaminopyridine)copper(II) Complex
(1997)
Behavior of N,N'-disalicylidene-2,3-diaminopyridine
(1) against metal ions'-3 and its X-ray structure4 as well as
its thermochromic and photochromic properties5 have
been reported. This communication presents the ...

Crystal Structure of Bis[4-(5-methyl-2-oxyphenyl-κO,2κO)-4-imino-2-penten-2-olato-O, O′,N′]copper(II)
(1997)
The title compound, Cu2(C12H13N02)2, is a doubly
oxygen-bridged dimeric copper(II) complex. Doubly
oxygen bridged complexes with subnormal magnetic
moments are known to exhibit super exchange interaction.l-3 The Cu atoms ...
Internal structure of composite systems described by infinite-component wave equations
(1977)
It is shown that the boson representation of infinite-component SO(4,2) wave equations represents a system of four oscillators as well as three-dimensional Kepler dynamics. These two pictures are complementary to each ...
Euler-form actions and the vanishing of the cosmological constant
(1989)
We investigate the conditions of the vanishing cosmological constant and the presence of gravity and vector gauge fields in a
D
-dimensional non-Abelian Kaluza-Klein theory based on a dimensionally continued ...
A physical realisation of the super-sine algebra
(1992)
An explicit physical realisation of the supersymmetric extension of the sine algebra generated by the symmetries of a spinless Bloch electron in a constant uniform magnetic field is given in terms of the symmetry operators ...
Light-curve and period changes of AB Andromedae
(1994)
New photoelectric observations of AB And obtained between 1989 and 1992 have been used, together with all available light curves from the literature, to study the light-curve variation of the system and its probable ...
Elemental abundance analyses with DAO spectrograms - XX. The early A stars ε Serpentis, 29 Vulpeculae and σ Aquarii
(1998)
Elemental abundances of the early A stars ε Ser, 29 Vul and σ Aqr are derived consistently with previous studies of this series using spectrograms obtained with Reticon and CCD detectors. The derived abundances confirm ...
