ABSTRACT: In the title compound, [Ni(C(7)H(3)Cl(2)O(2))(2)(C(3)H(7)NO)(H(2)O)], the Ni(II) ion is coordinated by four O atoms from two bidentate 2,4-dichloro-6-formyl-phenolate ligands, one O atom from a water ligand and one O atom from a dimethyl-formamide ligand in a slightly distorted octa-hedral environment. In the crystal structure, centrosymmetric dimers are formed though O-H⋯O and O-H⋯Cl hydrogen bonds; π-π stacking inter-actions, with a centroid-centroid distance of 3.796 (2) Å, are also found.

Project description:The crystal of the title compound, [Zn(C(7)H(3)Cl(2)O(2))(2)(H(2)O)(2)](2)·[Zn(2)(C(7)H(3)Cl(2)O(2))(4)(H(2)O)(2)], consists of monomeric and dimeric Zn(II) complexes. Both complexes afford a six-coordinated coordination environment about the Zn atoms with cis-configuration ligands. The deprotonated hydr-oxy groups of the 3,5-dichloro-salicylaldehyde ligands bridge two metal cations, forming a centrosymmetric dimeric complex. Inter-molecular O-H⋯O hydrogen bonding occurs between the coordinated water mol-ecules and deprotonated hydr-oxy groups in the crystal structure.

cis-[Aqua/methanol(0.45/1.55)](1,1,1-trifluoro-5,5-dimethyl-hexane-2,4-dionato)nickel(II)-cis-[aqua/methanol(1.49/0.51)](1,1,1-trifluoro-5,5-dimethyl-hexane-2,4-dionato)nickel(II) (1/1).

Project description:The title compound, [Ni(C(8)H(10)F(3)O(2))(2)(CH(4)O)(1.55)(H(2)O)(0.45)][Ni(C(8)H(10)F(3)O(2))(2)(CH(4)O)(0.51)(H(2)O)(1.49)], is an octa-hedral nickel(II) complex with two acetyl-acetonate-like 1,1,1-trifluoro-5,5-dimethyl-hexane-2,4-dionate ligands. The two chelating ligands are in cis positions with respect to each other and the remaining two adjacent coordination sites are taken up by water and methanol donor mol-ecules. In both crystallographically independent mol-ecules, each donor site shows disorder of methanol and water with occupancies of 0.51 (1) and 0.55 (1) in favor of methanol. The remaining two donor sites are not disordered and are water for the first and methanol for the second independent mol-ecule. Rotational disorder is observed for one of the tert-butyl groups, the occupancy rate for the major component here is 0.687 (9). O-H⋯O hydrogen bonds connect the two independent mol-ecules with each other and, across a crystallographic inversion center, they are combined with two neighboring mol-ecules to form a centrosymmetric hydrogen-bonded tetra-mer.

Bis(2,4-dibromo-6-formyl-phenolato-κO,O')copper(II).

Project description:In the title compound, [Cu(C(7)H(3)Br(2)O(2))(2)], the Cu(II) atom, which lies on an inversion centre, is coordinated by four O atoms from two chelating bidentate 2,4-dibromo-6-formyl-phenolate ligands in a slightly distorted square-planar coordination geometry. In the crystal structure, short inter-molecular Br⋯Br [3.516 (4) and 3.653 (4) Å] and Cu⋯Br [3.255 (1) Å] contacts together with C-H⋯O hydrogen bonds generate a three-dimensional network.

In addition, the crystal structure is stabilized by weak C-H⋯O and C-H⋯N hydrogen bonds.

Project description:The O-C(6)H(4)-CH=N-C(6)H(4)-O dianion of the title compound, [Mn(C(13)H(9)NO(2))(C(7)H(5)O(2))(C(2)H(6)OS)], acts as an O,N,O'-chelate to bind to the Mn(III) atom, and the three atoms constitute three points [O-Mn-O = 174.43 (11)°] of an octa-hedron around the metal atom. The azomethine linkage is disordered over two positions in a 0.657 (13):0.343 (13) ratio. The deprotonated salicyldehyde anion acts as an O,O'-chelate; the sixth coordination site is represented by the O atom of the dimethyl sulfoxide mol-ecule. The crystal studied was a non-merohedral twin with a minor twin component of 14.2 (3)%.

(3,5-Dichloro-salicylaldehyde thio-semi-carbazonato-κS,N,O)(N,N'-dimethyl-formamide-κO)copper(II) dimethyl-formamide solvate.

Project description:In the title compound, [Cu(C(8)H(5)Cl(2)N(3)OS)(C(3)H(7)NO)]·C(3)H(7)NO, the Cu(II) atom is coordinated in a slightly distorted square-planar geometry by an O, an S and an N atom from the tridentate ligand 3,5-dichloro-salicylaldehyde thio-semi-carb-azonate ligand and one O atom from dimethyl-formamide. At the same time, the Cu atom is in contact with S and Cl atoms from another two complexes [Cu⋯S and Cu⋯Cl = 2.9791 (2) and 3.3800 (3) Å, respectively], thereby forming a [4 + 2] coordination geometry. The crystal structure exhibits N-H⋯O and N-H⋯N hydrogen bonds.
