Pseudooctahedral mononuclear cobat(II) complex [Co(abpt)2(tcm)2] (1), where abpt = 4-amino-3,5-bis(2-pyridyl)-1,2,4-triazole and tcm = tricyanomethanide anion, shows field-induced slow relaxation of magnetization with U = 86.2 K and large axial and rhombic single-ion zero-field-splitting parameters, D = +48(2) cm(-1) and E/D = 0.27(2) (D = +53.7 cm(-1) and(More)
(Dicyanamido-κN(1))bis(5,5'-dimethyl-2,2'-bipyridine-κ(2)N,N')copper(II) tetrafluoroborate, [Cu{N(CN)2}(C12H12N2)2]BF4, (I), and (dicyanamido-κN(1))bis(5,5'-dimethyl-2,2'-bipyridine-κ(2)N,N')copper(II) perchlorate, [Cu{N(CN)2}(C12H12N2)2]ClO4, (II), are isomorphous and consist of [Cu{N(CN)2}(mbpy)2](+) cations (mbpy is 5,5'-dimethyl-2,2'-bipyridine) and(More)
The title compound, [CuBr(C(12)H(8)N(2))(2)][N(CN)(2)], is formed of discrete [CuBr(phen)(2)](+) complex cations and uncoordinated [N(CN)(2)](-) anions (phen is 1,10-phenanthroline). The Cu atom is five-coordinated in a distorted trigonal-bipyramidal geometry by two phen mol-ecules and one bromide ligand, which coordinates in the equatorial plane at a(More)
The title compound, [Cu(C(2)N(3))(C(12)H(8)N(2))(2)](CF(3)SO(3)), is formed by discrete [Cu(phen)(2)(N(CN)(2)))](+) complex cations (phen is 1,10-phenanthroline) and uncoordinated CF(3)SO(3)(-) anions. The Cu centre is five-coordinated in the form of a distorted trigonal bipyramid to two phen molecules and one dicyanamide ligand, which is coordinated(More)
The title compound, [Cu(C(2)N(3))(C(12)H(8)N(2))(2)]ClO(4), represents a relatively rare class of compounds with dicyanamide coordinated in a monodentate manner. The structure is formed by the [Cu{N(CN)(2)}(phen)(2)](+) complex cation (phen is 1,10-phenanthroline) and an uncoordinated ClO(4)(-) anion. The Cu atom is five-coordinate, with a slightly(More)
Two new diamagnetic coordination compounds, [Fe(phen)3][C(CN)3]2, (I), and [Fe(bpy)3][C(CN)3]2·1.5H2O, (II), have been synthesized and characterized by single-crystal X-ray diffraction analysis, and IR and UV-Vis spectroscopy (phen is 1,10-phenanthroline, C12H8N2, and bpy is 2,2'-bipyridine, C10H8N2). Both compounds are ionic with distorted octahedral(More)
The structure of the title compound, [Cu(C(6)H(7)N)(2)(Ag(CN)(2)(2)](n), is made up of neutral zigzag chains of [-NC-Ag-CN-Cu(4-Mepy)(2)(Ag(CN)(2))-NC-Ag-CN-] (4-Mepy is 4-methylpyridine). Neighbouring chains are linked by weak argentophilic interactions, with Ag.Ag distances of 3.2322 (12) A. The Cu atom, which lies on a twofold rotation axis, is(More)
Bis(5-chloro-8-hydroxyquinolinium) tetrachloridopalladate(II), (C(9)H(7)ClNO)(2)[PdCl(4)], (I), catena-poly[dimethylammonium [[dichloridopalladate(II)]-μ-chlorido]], {(C(2)H(8)N)[PdCl(3)]}(n), (II), ethylenediammonium bis(5-chloroquinolin-8-olate), C(2)H(10)N(2)(2+)·2C(9)H(5)ClNO(-), (III), and 5-chloro-8-hydroxyquinolinium chloride, C(9)H(7)ClNO(+)·Cl(-),(More)
In the title compound, [Cu(C(2)N(3))(C(10)H(8)N(2))(2)]BF(4), the Cu(II) atom shows distorted trigonal-bipyramidal geometry, with the dicyanamido ligand in the equatorial plane. The two out-of-plane Cu-N bond lengths to bipyridine are 2.006 (3) and 1.998 (3) A, whereas the in-plane Cu-N distances are 2.142 (3) and 2.043 (3) A to the bipyridine, and 2.015(More)
The title compound, [Fe(C14H12N2)3](C4N3)2, consists of one [Fe(dimephen)3](2+) complex cation (dimephen = 5,6-dimethyl-1,10-phenanthroline) and two uncoordinating tcm anions (tcm = tricyano-methanide). In the complex cation, the Fe(II) atom is coordinated by six N atoms from three chelating dimephen ligands at an average Fe-N distance of 1.963 (4) Å giving(More)
