Preparation of 6-azafulleroid-6-deoxy-2,3-di-O-myristoylcellulose.
6-Azafulleroid-6-deoxy-2,3-di-O-myristoylcellulose (3) was synthesized from 6-azido-6-deoxycellulose (1) by two reaction steps. The myristoylation of compound 1 with myristoyl chloride/pyridine proceeded smoothly to give 6-azido-6-deoxy-2,3-di-O-myristoylcellulose (2) in 97.0% yield. The reaction of compound 2 with fullerene (C(60)) was carried out by microwave heating to afford compound 3 in h...

In the title complex, [Dy(C(7)H(3)NO(4))(C(7)H(4)NO(4))](n), one of the ligands is fully deprotonated while the second has lost only one H atom. Each Dy(III) ion is coordinated by six O atoms and two N atoms from two pyridine-2,6-dicarboxyl-ate and two 6-carboxy-picolinate ligands, displaying a bicapped trigonal-prismatic geometry. The average Dy-O bond distance is 2.40 Å, some 0.1Å longer than...

The Rh(III) ion in the title compound, [Rh(C(12)H(6)N(2)O(4))(C(12)H(7)N(2)O(4))], is coordinated by four N atoms and two O atoms from two chelating ligands L and HL (H(2)L = 2,2'-bipyridine-6,6'-dicarb-oxy-lic acid) to form a distorted octa-hedral geometry. Face-to-face π-stacking inter-actions are observed between inversion-related pyridine rings, with a centroid-to-centroid distance of 3.581...

The Co(III) atom in the title compound, [Co(C(12)H(6)N(2)O(4))(C(12)H(7)N(2)O(4))], is six-coordinated in a distorted octa-hedral geometry by four N atoms and two O atoms of the chelating 2,2'-bipyridine-6,6'-dicarboxyl-ate and 6'-carb-oxy-2,2'-bipyridine-6-carboxyl-ate ligands. Intermolecular O-H⋯O hydrogen bonds and face-to-face π-stacking inter-actions [centroid-centroid distance = 3.6352 (1...

In the title compound, [Ni(C(12)H(7)N(2)O(4))(2)]·4H(2)O, the Ni atom is located at the centre of a distorted octa-hedron, formed by four N atoms and two O atoms from the same two tridentating chelated 6-carb-oxy-2,2'-bipyridine-6'-carboxyl-ate (L) ligands. Face-to-face π-stacking inter-actions between inversion-related pyridine rings with centroid-centroid distances of 3.548 (3) and 3.662 (3) ...
