The title compound, [Cu4(C11H13NO4)4]·CH3CH2OH·2.5H2O, is an electronically neutral tetra-nuclear copper(II) complex with a cubane-like Cu4O4 core. The complete molecule has point group symmetry 2. The phenol hy-droxy group and one of the three alcohol hy-droxy groups of each 2-{[tris-(hy-droxy-meth-yl)meth-yl]imino-meth-yl}phenol ligand are depro-ton-ated,(More)
In the centrosymmetric title compound, [Co(C6H12N4O3)2](NO3)2·4H2O, the Co(II) ion, lying on an inversion center, is O,N,O'-chelated by two nitrilo-triacetamide mol-ecules, forming a distorted octa-hedral geometry. In the crystal, extensive O-H⋯O and N-H⋯O hydrogen bonds link the complex cations, nitrate anions and lattice water mol-ecules into a(More)
The title compound, [Ni(4)(C(6)H(5)N(3)O)(2)(C(6)H(6)N(3)O)(2)(C(5)H(5)N)(4)](NO(3))(2), is a tetra-nuclear nickel complex containing a single-decker cation, located on an inversion center. The two unique Ni(II) cations are N,N',N'',O-chelated by carbox-imid-amid-ate(2-) and carboximidamidate(1-) anions, forming a distorted four-coordinate planar structure,(More)
In the title dinuclear compound, [Zn(2)(C(6)H(6)N(3)O)(2)(C(6)H(7)N(3)O)(2)](NO(3))(2), the Zn(II) cation is N,N'-chelated by one pyridine-2-carboxamide oximate anion and one pyridine-2-carboxamide oxime mol-ecule, and is further bridged by an oxime O atom from the adjacent pyridine-2-carboxamide oximate anion, forming a distorted trigonal bipyramidal(More)
