چکیده
The title complex, [Ni(4)(C(12)H(15)NO(4))(4)]·4H(2)O, has crystal-lographic fourfold inversion symmetry, with each Ni(II) ion coordinated in a slightly distorted square-pyramidal coordination environment and forming an Ni(4)O(4) cubane-like core. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds connect complex and water mol-ecules to form a three-dimensional network. The O atom of one of the unique hydroxy-methyl groups is disordered over two sites, with the ratio of occupancies being approximately 0.79:0.21.

The title cluster, [Cu4(C11H12N2O6)4], was obtained from the Cu(0)-FeCl2·4H2O-H4 L-Et3N-DMF reaction system (in air), where H4 L is 2-hy-droxy-methyl-2{[(2-hy-droxy-3-nitro-phen-yl)methyl-idene]amino}-propane-1,3-diol and DMF is di-methyl-formamide. The asymmetric unit consists of one Cu(2+) ion and one dianionic ligand; a -4 symmetry element generates the cluster, which contains a {Cu4O4} cuba...

The title complex, [Ni(4)(C(36)H(40)N(2)O(2))(2)(OH)(4)(C(3)H(9)OP)(2)(H(2)O)(4)]·2C(4)H(10)O·2C(3)H(9)OP·2H(2)O, is centrosymmetric with a central core that can be described as a defect double cubane. The four metal ions in the cluster are held together by four bridging hydroxide groups. Each Ni(II) atom adopts a distorted octa-hedral geometry.

The Schiff base ligand in the title compound, [Sn(C(4)H(9))(2)(C(11)H(12)ClNO(4))], chelates to the Sn atom through the two deprotonated O atoms, as well as through the N atom, to confer an overall cis-C(2)SnNO(2) trigonal-bipyramidal geometry at tin [C-Sn-C = 130.3 (1)°]. The hydr-oxy groups engage in O-H⋯O hydrogen bonding with the O atoms of adjacent mol-ecules, generating a chain running al...

The crystal structure of the tetra-nuclear title compound, [Cu4(C12H15NO5)4(H2O)4], has been previously reported by Back, Oliveira, Canabarro & Iglesias [Z. Anorg. Allg. Chem. (2015), 641, 941-947], based on room-temperature data. In the previously published structure, no standard uncertainties are recorded for the deprotonated hy-droxy-methyl group and water mol-ecule O atoms coordinating to t...
