In the title compound, [Cd(NO(3))(2)(C(22)H(30)N(2)O(4))], the Cd(II) atom is eight-coordinated by two amine N atoms and two O atoms from the 5,6:19,20-dibenzo-1,4,11,14-tetra-oxa-8,17-diaza-cyclo-eicosane ligand and four O atoms from two nitrate groups. The coordination geometry about Cd is antiprismatic. One nitro O atom is disordered equally over two positions.

The tin(IV) atom in the salt, (C(7)H(11)N(2))(2)[SnBr(2)(CH(3))(2)Cl(2)], lies on a center of inversion in a tetra-gonally compressed octa-hedron; the bromine atoms are disordered with the chlorine atoms, so that they appear to share the same site. The crystal structure is stabilized by N-H⋯Br hydrogen bonds.

In the title complex, [Mn(C(11)H(10)N(3)O(2))(2)]·3H(2)O, the Mn(II) atom is coordinated by four N atoms and two O atoms in a distorted octa-hedral geometry. The mol-ecules are linked together via hydrogen bonds involving the water molecules. One of these is disordered equally over two positions.

In the title compound, [Zn(C(21)H(25)N(3)O(2))], the Zn(II) atom is five-coordinate from three N donor atoms and two O donor atoms of the dianion ligand in a distorted trigonal-bipyramidal arrangement. Three methyl-ene groups of the ligand are disordered over two orientations in a 0.555 (6):0.445 (6) ratio.

In the mol-ecule of the title compound, C(8)H(6)BrI, the H atoms of methyl groups are disordered; site-occupation factors were fixed at 0.50. The non-H atoms all lie on a crystallographic mirror plane. Weak intra-molecular C-H⋯Br hydrogen bonds result in the formation of two non-planar five-membered rings.

In the dinuclear salen-type title complex, [CuNa(BF(4))(C(18)H(18)N(2)O(4))(CH(3)OH)], the Cu(II) atom is chelated by two O atoms and two N atoms of the deprotonated Schiff base in a square-planar geometry. The Na atom is seven-coordinate as it is linked to four O atoms of the same Schiff base ligand, one O atom of the methanol and two tetra-fluorido-borate F atoms. The remaining two F atoms of...

In the title compound, [Cu(2)Mn(C(5)HN(2)O(4))(2)(H(2)O)(6)](n), the Cu(II) ion is coordinated by two N atoms, two O atoms and one water O atom in a distorted square-pyramidal geometry. The Mn(II) ion is coordinated by two O atoms and four water O atoms in a distorted octa-hedral geometry. Two pyrazolyl-3,5-dicarboxyl-ate anions chelate to two copper ions, forming a dinuclear unit, which furthe...

In the title heterodinuclear complex, [CuNa(BF(4))(C(8)H(7)O(3))(2)](n), the Cu(II) ion is four-coordinated by four O atoms of two 2-formyl-6-meth-oxy-phenolate ligands, giving rise to a square-planar geometry. The Na(+) ion is six-coordinated by four O atoms from the two ligands and two F atoms of two tetra-fluoridoborate anions. The tetra-fluoridoborate anion links the Na(+) ions, forming a o...

The title compound, [Al(C5H8N2)Cl3], was prepared by a thermolytic decomposition under high-vacuum conditions and presents a formal adduct of an Arduengo carbene, 1,3-dimethyl-1H-imidazol-2-yl-idene, and aluminium trichloride. The Al atom adopts a pseudo-tetra-hedral CCl3 coordination environment. All N and C atoms, the Al atom, one of the Cl atoms, and all aromatic H atoms of the mol-ecule lie...
