Highly luminescent zinc(II)-bis(8-hydroxyquinoline) (Znq(2)) complex nanorods have been synthesized via a sonochemical route from the microemulsion containing zinc acetate and 8-hydroxyquinoline. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images showed that the products were rod-like morphology with a diameter of about(More)
Four isostructural metal organic frameworks (MOFs), namely [Co6(HipO)6]·6H2O (1), [Mn6(HipO)6]·6H2O (2), [Cd6(HipO)6]·6H2O (3) and [Zn6(HipO)6]·7H2O (4) (H3ipO = 2-hydroxyisophthalic acid), were synthesized and structurally characterized. They have a 3D (4,6)-connected framework based on [24-MC-6] metallacrown clusters ([24-MC-6]-based MOFs). The(More)
In the title trinuclear Ni(II) compound, [Ni(3)(C(18)H(19)N(2)O(3))(2)(C(5)H(5)N)(4)]·C(3)H(7)NO·H(2)O, three Ni(II) cations are bridged by two N'-(adamantan-1-ylcarbon-yl)-2-oxidobenzohydrazidate trianions. The central Ni(II) cation has a distorted octa-hedral N(4)O(2) coordination environment where a reverse torsion occurs between the two bridging(More)
The title nickel(II) coordination polymer, viz. poly[[bis(1,10-phenanthroline)tris(mu3-1,4-phenylenediacetato)trinickel(II)] dihydrate], {[Ni3(C10H8O4)3(C12H8N2)2].2H2O}(n), consists of linear trinuclear building blocks with two crystallographically unique Ni atoms. One Ni(II) atom and the geometric centre of one 1,4-phenylenediacetate ligand in the(More)
In the title polymeric complex, [Cd(C 5 H 4 NO 3 S) 2 (H 2 O) 2 ] n , the Cd atom is located on a centre of inversion and is coordinated by two O atoms and two N atoms, derived from four different pyridine-3-sulfonate ligands, and two O atoms derived from two water molecules, forming a distorted trans-N 2 O 4 octa-hedral geometry. The topology of the(More)
In the title complex, [CuCl(2)(C(24)H(24)N(2)O(2))], the Cu(II) cation is N,N',O-chelated by a 2,2'-(1,1'-binaphthyl-2,2'-diyldiimino)-diethanol ligand and coordinated by two chloride anions in a distorted square-pyramidal geometry. In the diethanol ligand, the two naphthalene ring systems are twisted with respect to each other at a dihedral angle of 68.30(More)
In the title polymeric complex, [Mn(C(5)H(4)NO(3)S)(2)(H(2)O)(2)](n), the Mn atom is located on a centre of inversion and is coordinated by two O atoms and two N atoms derived from four different pyridine-3-sulfonate (pySO(3)) ligands, and two O atoms derived from two water mol-ecules in a distorted trans-N(2)O(4) octa-hedral geometry. The metal atoms are(More)
The reaction of M(II) ions with azido ligands in the presence of different amino carboxylic acids gave four three-dimensional metal-azido coordination polymers, [Mn(3,5-daba)(N(3))](n) (1), [Cd(3,5-daba)(N(3))](n) (2; 3,5-daba = 3,5-diaminobenzoate), [Mn(4-aba)(N(3))](n) (3; 4-aba = 4-aminobenzoate), and [Cu(2)(gly)(2)(N(3))(2)](n) (4; gly = glycinate),(More)
An unprecedented {Gd18} nanowheel was solvothermally synthesized with a novel diacylhydrazone ligand. It features a rare single-stranded skeleton just like a Reuleaux triangle with vertices buckled in, represents the highest nuclearity and largest size in lanthanide (Ln) wheels reported so far, and shows a large magnetocaloric effect (MCE).
In the title compound, [Gd(C(8)H(6)NO(2))(3)(H(2)O)](n), the gadolinium(III) ion is coordinated by eight carboxyl-ate O atoms and one water mol-ecule. The carboxyl-ate ligands bridge pairs of gadolinium(III) ions, forming a zigzag chain along [100]. Hydrogen bonds link the chains into sheets parallel to (001).
