Hexaaqua-copper(II) dichloride bis-(hexa-methyl-enetetra-mine) tetra-hydrate.

ABSTRACT: The title compound, [Cu(H(2)O)(6)]Cl(2)·2C(6)H(12)N(4)·4H(2)O, was prepared under mild hydro-thermal conditions. The asymmetric unit consists of one half of the [Cu(H(2)O)(6)](2+) cation, a hexa-methyl-enetetra-mine mol-ecule, two solvent water mol-ecules and a chloride ion. The formula unit is generated by crystallographic inversion symmetry. The Cu atom lies on a crystallographic inversion centre. It is in a slightly distorted octa-hedral coordination environment. In the crystal structure, inter-molecular O-H⋯O, O-H⋯N and O-H⋯Cl hydrogen bonds link the components into a three-dimensional network.

Hexaaqua-zinc(II) dichloride bis-(hexa-methyl-enetetramine) tetra-hydrate.

Project description:The title compound, [Zn(H(2)O)(6)]Cl(2)·2C(6)H(12)N(4)·4H(2)O, has been prepared under mild hydro-thermal conditions. The Zn(II) atom, located on a centre of symmetry, is coordinated by six water mol-ecules in a distorted octa-hedral coordination geometry. The hexa-methyl-enetetra-mine mol-ecule is not coordinated to Zn(II) but links the Zn complexes via three O-H?N hydrogen bonds. The remaining N atom of the hexa-methyl-enetetra-mine mol-ecule is hydrogen-bonded to a solvent water mol-ecule. In the crystal structure, inter-molecular O-H?O, O-H?N and O-H?Cl hydrogen bonds link the components into a three-dimensional network.

Bis(hexa-methyl-enetetra-mine)bis-(tri-chloro-acetato)copper(II).

Project description:In the title compound, [Cu(C(2)Cl(3)O(2))(2)(C(6)H(12)N(4))(2)], the Cu(II) ion (site symmetry 2) is coordinated by two trichloro-acetate anions and two hexa-methyl-enetetra-mine mol-ecules, resulting in a distorted CuN(2)O(2) geometry that is inter-mediate between tetra-hedral and square planar. The Cl atoms are disordered over two sets of sites, with relative occupancies of 0.749?(7) and 0.251?(7). In the crystal, the packing is consolidated by inter-molecular C-H?O inter-actions.

Hexaaqua-manganese(II) bis-{[N-(3-meth-oxy-2-oxidobenzyl-idene)glycylglycinato]copper(II)} hexa-hydrate.

Project description:The ligand N-(2-hydr-oxy-3-methoxy-benzyl-idene)glycylglycine (H(3)L), a Schiff base derived from glycylglycine and 3-methoxy-salicylaldehyde, was used in the synthesis of a new organic-inorganic coordination complex, [Mn(H(2)O)(6)][Cu(C(12)H(11)N(2)O(5))](2)·6H(2)O. The Mn(II) atom is located on an inversion center and is coordinated to six water mol-ecules in a slightly distorted octa-hedral geometry. The Cu(II) atom is chelated by the tetra-dentate Schiff base ligand in a distorted CuN(2)O(2) square-planar coordination. In the crystal structure, the complex [Mn(H(2)O)(6)](2+) cations and the [CuL](-) anions are arranged in columns parallel to the a axis and are held together by O-H⋯O hydrogen bonding. Additional hydrogen bonds of the same type further link the columns into a three-dimensional network.

Dicarbon-yl(?(5)-cyclo-penta-dien-yl)(hexa-methyl-enetetra-mine-?N(1))iron(II) tetra-fluoridoborate.

Project description:In the structure of the title compound, [Fe(C(5)H(5))(C(6)H(12)N(4))(CO)(2)]BF(4), the arrangement around the Fe(II) atom corresponds to that of a three-legged piano stool. The cyclo-penta-dienyl ligand occupies three coordination sites of the apical position in a ?(5) fashion, while two CO ligands and one N atom of the hexa-methyl-ene-tetra-mine ligand occupy the remaining coordination sites to complete a distorted octa-hedral geometry. The asymmetric unit consists of two sets of crystallographically independent cations and anions with the r.m.s. deviations of the overlay of non-H atoms of each pair being 0.081 and 0.120?Å, respectively. The Fe-N bond lengths are 2.0459?(15) and 2.0490?(14)?Å, while the Fe-Cp(centroid) distances are 1.7257?(3) and 1.7246?(3)?Å. One of the anions displays disorder, with the F atoms having occupancies of 0.58?(4) and 0.42?(4).

4,4',6,6'-Tetra-methyl-2,2'-bipyrimidine hexa-hydrate.

Project description:In the title compound, C(12)H(14)N(4)·6H(2)O, the two pyrimidine rings make a dihedral angle of 5.285 (6)°. Inter-molecular O-H⋯O hydrogen bonds link the six water mol-ecules, generating edge-fused four-, five- or six-membered ring motifs and forming two-dimensional sheets. The sheets are stabilized by the formation of O-H⋯N hydrogen bonds between the water mol-ecules and the bipyrimidine mol-ecules, resulting in a three-dimensional network.
