A New Metalloligand Powerful in Forming Helical Coordination Polymers
A new macrocyclic oxamido carboxylate metalloligand was designed and three heteronuclear coordination polymers of the metalloligand and metal nodes Cu2+, Zn2+ and Cd2+ were prepared. X-ray single crystal analyses...

Two heterometallic complexes with a new macrocyclic oxamido complex ligand
A new macrocyclic oxamido-nickle(II) complex Na2NiL was synthesized. L denotes the doubly deprotonated forms of (13Z, 19Z)-16-methyl-6,7-dioxo-5,6,7,8-tetrahydrotriben-zo[b,f,l][1,4,8,11]tetraazacyclotetradecine-...

Structure and magnetism of Co:CoO core–shell nanoclusters
Transmission electron microscopy (TEM) and electron diffraction (ED) are used to investigate the nanostructures of two ensembles of Co:CoO core–shell particles. TEM images show that particles of size about 12 ...

Structural relation between a 2D fivefold quasicrystal and crystalline approximants in an Al–Co–Ni–Tb alloy
A two-dimensional quasicrystal with fivefold symmetry and two large-unit-cell crystalline approximants in an Al–Co–Ni–Tb alloy, which were observed in previous studies, are suggested to be composed of the same...

Transformation of Al–Ni–(Si) decagonal quasicrystals to 1–D quasicrystal and crystalline approximants
Rapidly quenched Al86-xNi14Six (x = 0, 2, 6, and 10) alloys have been studied by means of transmission electron microscopy. Two-dimensional (2-D) decagonal quasicrystal with a periodicity of 1.6 nm along its tenf...
