(Diethyl-enetriamine)bis-(theophyllinato)zinc(II) dihydrate.

ABSTRACT: In the title compound, [Zn(C(7)H(7)N(4)O(2))(2)(C(4)H(13)N(3))]·2H(2)O, the Zn(II) ion is penta-coordinated by three N atoms of the diethyl-enetriamine ligand and one N atom of each of the two theophyllinate anions in a distorted trigonal-bipyramidal geometry. The Zn-N distances range from 2.076?(3) to 2.221?(3)?Å. The crystal packing is stabilized by O-H?O, O-H?N and N-H?O hydrogen bonds involving the theophylline and diethyl-enetriamine ligands and uncoordinated water mol-ecules.

Project description:In the centrosymmetric title complex, [Zn(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Zn(II) atom is located on an inversion center.

Tetra-kis[?-4-(methyl-amino)-benzoato-?O:O']bis-[(N,N-diethyl-nicotinamide-N)zinc(II)] dihydrate.

Project description:The title mol-ecule, [Zn(2)(C(8)H(8)NO(2))(4)(C(10)H(14)N(2)O)(2)]·2H(2)O, is a centrosymmetric binuclear complex, with two Zn(II) ions [Zn?Zn' = 2.9301?(4)?Å] bridged by four methyl-amino-benzoate (MAB) ligands. The four nearest O atoms around each Zn(II) ion form a distorted square-planar arrangement with the distorted square-pyramidal coordination completed by the pyridine N atom of the N,N-diethyl-nicotinamide (DENA) ligand. Each Zn(II) ion is displaced by 0.3519?(2)?Å from the plane of the four O atoms, with an average Zn-O distance of 2.030?Å. The dihedral angles between carboxyl-ate groups and adjacent benzene rings are 10.57?(10) and 16.63?(12)°, while the benzene rings are oriented at a dihedral angle of 81.84?(5)°. The pyridine ring is oriented at dihedral angles of 40.49?(6) and 51.25?(6)° with respect to the benzene rings. In the crystal structure, inter-molecular O-H?O and N-H?O hydrogen bonds link the mol-ecules into a three-dimensional network. The ?-? contact between the inversion-related pyridine rings [centroid-centroid distance = 3.633?(1)?Å] may further stabilize the crystal structure.

Crystal structure of bis-(piperazin-1-ium-κN4)bis-(thio-sulfato-κS)zinc(II) dihydrate.

Project description:In the title compound, [Zn(C4H11N2)2(S2O3)2]·2H2O, two thio-sulfate ions coordinate to the zinc(II) atom through the terminal S atoms. The tetra-hedral coordination around the ZnII ion is completed by ligating to two N atoms of two piperazinium ions. The remaining two N atoms of the piperazinium ions are diprotonated and do not coordinate to the metal centre. In the crystal, however, they are involved in N-H⋯Owater and N-H⋯Osulfato hydrogen bonds. Together, a series of N-H⋯O and O-H⋯O hydrogen bonds, involving the O atoms of the thio-sulfate ions and the water mol-ecules as acceptors and the hydrogen atoms of the piperazinium ions and the water mol-ecules as donors, form a three-dimensional supra-molecuar structure. Within this framework there are a number of intra- and inter-molecular C-H⋯O and C-H⋯S contacts present.

Project description:The title compound, [Zn(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], is a monomeric complex with the Zn(II) atom lying on an inversion center.

The four O atoms in the equatorial plane around the Zn atom form a slightly distorted square-planar arrangement, while the distorted octa-hedral geometry is completed by two N atoms in the axial positions. The methyl group of one of the ethyl groups is disordered over two positions, with occupancies of ca 0.65 and 0.35. The two aromatic rings are oriented at an angle of 77.22?(14)°. In the crystal structure, O-H?O hydrogen bonds link the mol-ecules into chains along the a axis.
