Bis[(1-ammonio-ethane-1,1-di-yl)diphospho-nato-?O,O']diaqua-nickel(II) nona-hydrate.

ABSTRACT: The title compound, [Ni(C(2)H(8)NO(6)P(2))(2)(H(2)O)(2)]·9H(2)O, exhibits a slightly distorted octa-hedral coordination environment around the Ni(II) atom. It contains two mol-ecules of 1-amino--ethyl-idenediphospho-nic acid in the zwitterionic form, coord-inated via O atoms from two phospho-nate groups and creating two six-membered chelate rings. Two water mol-ecules in cis positions complete the coordination environment of the Ni(II) atom. The title compound contains nine partly disordered solvent water mol-ecules, which create a three-dimensional network of strong O-H?O and N-H?O hydrogen bonds.

trans-Bis[(1-ammonio-pentane-1,1-di-yl)diphospho-nato-?O,O']diaqua-copper(II).

Project description:In the title compound, [Cu(C(5)H(14)NO(6)P(2))(2)(H(2)O)(2)], the Cu(II) atom occupies a special position on an inversion centre. It exhibits a distorted octa-hedral coordination environment consisting of two O,O'-bidentate (1-ammonio-pentane-1,1-di-yl)diphospho-nate anions in the equatorial plane and two trans water mol-ecules located in axial positions. The ligand mol-ecules are coordinated to the Cu(II) atom in their zwitterionic form via two O atoms from different phospho-nate groups, creating two six-membered chelate rings with a screw-boat conformation. The CuO(6) coordination polyhedron is strongly elongated in the axial direction with 0.6?Å longer bonds than those in the equatorial plane. Intra-molecular N-H?O hydrogen bonding helps to stabilize the mol-ecular configuration. The presence of supra-molecular -PO(OH)?O(OH)P- units parallel to (100) and other O-H?O and N-H?O hydrogen bonds establish the three-dimensional set-up.

Bis(1-ammonio-ethane-1,1-diyl-diphos-phonato-?O,O')diaqua-cobalt(II) nona-hydrate.

Project description:In the title compound, [Co(C(2)H(8)NO(6)P(2))(2)(H(2)O)(2)]·9H(2)O, the Co(II) atom has a slightly distorted octa-hedral coordination environment consisting of four deprotonated phospho-nate O atoms of two independent 1-amino-ethyl-idendiphospho-nate anions and complemented by the O atoms of two water mol-ecules in cis positions. The anions exists in the zwitterionic form (protonated amino group and two deprotonated phospho-nate O atoms) and constitute two six-membered chelate rings. The crystal structure also contains nine partly disordered uncoordinated water mol-ecules, which create an extensive three-dimensional network of strong O-H?O and N-H?O hydrogen bonds.

Poly[[?-(1-ammonio-ethane-1,1-di-yl)bis-(hydrogenphospho-nato)]diaquachloridodisodium]: a powder X-ray diffraction study.

Project description:The title compound, [Na(2)(C(2)H(8)NO(6)P(2))Cl(H(2)O)(2)](n), has a polymeric two-dimensional structure extending parallel to (001). The asymmetric unit contains two Na(+) cations located on a centre of symmetry and on a mirror plane, respectively, one half of a bis-phospho-nate anion (the entire anion is completed by mirror symmetry), one chloride anion on a mirror plane and one water mol-ecule in general positions. The two Na(+) cations exhibit distorted octa-hedral NaCl(2)O(4) coordination polyhedra, each consisting of two deprotonated O atoms of the bis-phospho-nate anion, of two water mol-ecules and of two chloride anions. Strong O-H?O hydrogen bonds between the -OH group and one of the free O atoms of the bis-phospho-nate anion connect adjacent layers along [100], supported by N-H?Cl inter-actions. Intra-layer O-H?O and N-H?O hydrogen bonds are also observed.

Diaqua-bis{[1-hydr-oxy-2-(1H-imidazol-3-ium-1-yl)ethane-1,1-di-yl]bis-(hydrogen phospho-nato)}manganese(II).

Project description:In the title compound, [Mn(C(5)H(9)N(2)O(7)P(2))(2)(H(2)O)(2)], the Mn(II) atom (site symmetry ) is coordinated by four phos-pho-n-ate O atoms from a pair of partially deprotonated 1-hydr-oxy-2-(imidazol-3-yl)ethane-1,1-bis-phophonic acid ligands (imhedpH(3) (-)) and two water mol-ecules, resulting in a slightly distorted trans-MnO(6) octa-hedral geometry for the metal ion. In the ligands, the imidazole units are protonated and two of the hydr-oxy O atoms of the phospho-nate groups are deprotonated and chelate the Mn(II), thus forming the neutral mol-ecule of the title compound. The two protonated O atoms within the phospho-nate groups of one imhedpH(3) (-) ligand act as hydrogen-bond acceptors for a bifurcated hydrogen bond originating from the coordinated water mol-ecule. The phospho-nate units of neigboring mol-ecules are connected with their equivalents in neighboring mol-ecules via two types of inversion-symmetric hydrogen-bonding arrangements with four and two strong O-H?O hydrogen bonds, respectively. The two inter-actions connect mol-ecules into infinite chains along [111] and [110], in combination forming a tightly hydrogen-bonded three-dimensional supra-molecular network. This network is further stabilized by additional hydrogen bonds between the protonated imidazole units and one of the coordinated P-O O atoms and by additional O-H?O hydrogen bonds between the water mol-ecules and the P=O O atoms of neigboring mol-ecules.

[?-2,3,5,6-Tetra-kis(2-pyrid-yl)pyrazine-?N,N,N:N,N,N]bis-[diaqua(dihydrogen m-phenylene-diphospho-nato-?O)nickel(II)] dihydrate.

Project description:The title compound [Ni(2)(C(6)H(6)O(6)P(2))(2)(C(24)H(16)N(6))(H(2)O)(4)]·2H(2)O or [Ni(2)(tpyprz)(1,3-HO(3)PC(6)H(4)PO(3)H)(2)(H(2)O)(4)]·2H(2)O [tpyprz = tetra-kis-(2-pyrid-yl)pyrazine, C(24)H(16)N(6)] is a binuclear complex with a crystallographic inversion center located at the center of the pyrazine ring. The equivalent nickel(II) sites exhibit a distorted {NiO(3)N(3)} octa-hedral coordination, with the three nitro-gen donors of each terminus of the tpyprz ligand in a meridional orientation. An aqua ligand occupies the position trans to the pyrazine nitro-gen donor, while the second aqua ligand is trans to the oxygen donor of the dihydrogen-1,3-phenyl-diphospho-nate ligand. The Ni-O and Ni-N bond lengths fall in the range 2.011?(3) to 2.089?(3)?Å. The protonation sites on the organo-phospho-nate ligand are evident in the significantly longer P-O bonds compared to the unprotonated sites. In the crystal structure, the complex mol-ecules and the solvent water mol-ecules are linked into a three-dimensional hydrogen-bonded framework through O-H?O inter-actions between the aqua ligands, the protonated organo-phospho-nate oxygen atoms and the water mol-ecules of crystallization. Intra-molecular ?-stacking between the phenyl group of the phospho-nate ligand and a pyridyl group of the tpyprz ligand, at a distance of 3.244?(5)?Å between ring centroids, is also observed.
