Bis[4-amino-N-(4-methyl-pyrimidin-2-yl-?N (3))benzene-sulfonamidato-?N](2,2'-bi-pyridine-?(2) N,N')mercury(II).

ABSTRACT: The complete mol-ecule of the title complex, [Hg(C11H11N4O2S)2(C10H8N2)], is generated by crystallographic twofold symmetry, with the mercury cation lying on the rotation axis. The mercury coordination polyhedron can be described as tetra-hedral (from the N,N'-bidenate bi-pyridine mol-ecule and the sulfonamide N atoms of the sulfamerazine anions) or as squashed trigonal-prismatic, if two long (> 2.80?Å) Hg-N bonds to pyrimidine N atoms are included. The dihedral angle between the aromatic rings in the anion is 73.3?(2)°. In the crystal, N-H?(N,O) and N-H?N hydrogen bonds link the mol-ecules into a three-dimensional network.

Project description:In the title compound, [Cd(C(10)H(9)N(4)O(2)S)(2)(C(12)H(12)N(2))]·2C(3)H(7)NO, the Cd(II) ion lies on a twofold rotation axis, is six-coordinated by N atoms, and displays a trigonal-prismatic geometry arising from the two sulfadiazinate ligands and one 4,4'-dimethyl-2,2'-bipyridine ligand. Both ligands are bidentate and coordinate via their N atoms. The O and carbonyl C atoms of the dimethyl-formamide mol-ecule show disorder and were modelled with two different orientations and with site occupancies of 0.584?(10):0.416?(10). The geometry around the sulfadiazine S atom is distorted tetra-hedral. The crystal structure involves N-H?O hydrogen bonds which link mol-ecules into a three-dimensional network. Weak C-H?O hydrogen bonds are also observed.

Project description:The title complex, [Co(C(10)H(9)N(4)O(2)S)(2)(C(3)H(7)NO)(2)], lies across an inversion center. The Co(II) atom is coordinated in a slightly distorted octa-hedral geometry by four N atoms from two bidentate 4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidate (sulfadiazine) anions and two O atoms from two dimethyl-formamide (DMF) ligands. The dihedral angle between the benzene and pyrimidine rings is 82.37?(13)°. A three-dimensional network is generated by N-H?O hydrogen bonds between the amino groups and of the sulfonamidate O atoms of neighbouring mol-ecules. The DMF ligand is disordered over two sets of sites in a 0.559?(4):0.441?(4) ratio.

Crystal structure of bis-(2,2'-bi-pyridine-κ(2) N,N')bis-(thio-cyanato-κN)mang-anese(II) 2,2'-bi-pyridine monosolvate.

Project description:In the crystal structure of the mononuclear title compound, [Mn(NCS)2(C10H8N2)2]·C10H8N2, the Mn(II) cation is coordin-ated in an all-cis configuration by two N-bound thio-cyanate anions and two 2,2'-bi-pyridine ligands within a slightly distorted octa-hedral environment. The asymmetric unit consists of one Mn(II) cation, two thio-cyanate anions and two 2,2'-bi-pyridine ligands, as well as two non-coordinating 2,2'-bi-pyridine ligands that are each located on centres of inversion. In the crystal structure, the discrete [Mn(NCS)2(C10H8N2)2] complex mol-ecules are arranged in such a way that cavities are formed, in which the solvent 2,2'-bi-pyridine mol-ecules are located. Apart from van der Waals forces, there are no remarkable inter-molecular inter-actions present in the crystal structure.

catena-Poly[neodymium(III)-bis-[?-N-(dimorpholinophosphor-yl)benzene-sulfonamidato]-sodium(I)-bis-[?-N-(dimorpholinophosphor-yl)benzene-sulfonamidato]].

Project description:The cubic crystal structure of the title compound, [NaNd(C(14)H(21)N(3)O(5)PS)(4)](n), is composed of one-dimensional polymeric chains propagating in [100], built up from [Nd(C(14)H(21)N(3)O(5)PS)(4)](-) anions and sodium cations functioning as linkers. In the complex anion, the Nd(3+) ion has an eightfold coordination environment formed by the sulfonyl and phosphoryl O atoms of four bidentate chelating N-(dimorpholinophosphor-yl)benzene-sulfonamidate ligands: the resulting NdO(8) polyhedron can be described as inter-mediate between dodeca-hedral and square anti-prismatic. The sodium ion adopts an NaO(4) tetra-hedral geometry arising from four monodentate benzene-sulfonamidate ligands. The resulting crystal structure is unusual because it contains substantial voids (800?Å(3) per unit cell), within which there is no evidence of included solvent.

Bis[4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidato]-?N,N';?N-aqua-bis-(dimethyl-formamide-?O)cadmium(II) monohydrate.

Project description:In the title compound, [Cd(C(10)H(9)N(4)O(2)S)(2)(C(3)H(7)NO)(2)(H(2)O)]·H(2)O, the Cd(II) ion displays a grossly distorted octa-hedral (or irregular) mer-CdN(3)O(3) coodination polyhdron arising from its coordination by one N,N'-bidentate sulfadiazinate anion, one monodentate sulfadiazinate anion, two O-bonded dimethyl-formamide molecules and one water mol-ecule. A short Cd?N contact [2.890?(3)?Å] to the monodentate sulfadiazinate ion also occurs. The dihedral angles between the planes of the aromatic rings of the anions are 86.81?(14) and 68.65?(14)°. The crystal structure features inter-molecular N-H?O, O-H?O and O-H?N hydrogen bonds.
