Tetraaquadiimidazolenickel(II) naphthalene-1,5-disulfonate
The triclinic unit cell of the title compound, [Ni(C(3)H(4)N(2))(2)(H(2)O)(4)](C(10)H(6)O(6)S(2)), contains one centrosymmetric cation and one centrosymmetric anion. In the cation, the Ni(II) ion is six-coordinated by two imidazole ligands [Ni-N = 2.0568 (14) Å] and four water mol-ecules [both independent Ni-O distances are 2.098 (1) Å] in a distorted octa-hedral geometry. Inter-molecular O-H⋯O...
متن کاملZn(II)-coordination and fluorescence studies of a new polyazamacrocycle incorporating 1H-pyrazole and naphthalene units.
The synthesis and Zn(2+) coordination properties of a new macrocycle (L1) obtained by dipodal (2 + 2) condensation of the polyamine 3-(naphthalen-2-ylmethyl)pentane-1,5-diamine with 1H-pyrazole-3,5-dicarbaldehyde are reported. pH-metric studies show that L1 bears five measurable protonation steps in the 2.0-11.0 pH range. Fluorescence emission studies indicate that the removal of the first prot...
متن کاملTechniques of lower limb prosthetic manufacture using Lightcast II.
In almost all cases the Ot to Bock modular endoskeletal prosthetic system has been used. This is the au thors ' choice of system, however the technique can be easily modified t o suit all modula r systems provided that the same principles of a t tachment of the modula r hardware to the Lightcast I I socket are followed. A Lightcast II socket can also be incorporated in an exoskeletal prosthesis...
متن کاملHexaaquacobalt(II) 2,2′-[naphthalene-1,8-diylbis(oxy)]diacetate dihydrate
In the title compound, [Co(H(2)O)(6)](C(14)H(10)O(6))·2H(2)O, the 2,2'-[naphthalene-1,8-diylbis(-oxy)]diacetate dianion L is not coordinated to the Co(II) ion. The asymmetric unit contains half of the L dianion, half of a [Co(H(2)O)(6)](2+) cation (both molecules being completed by inversion symmetry), and one water mol-ecule. The crystal packing features O-H⋯O hydrogen bonding between the carb...
متن کاملTris(ethylenediamine-κ2 N,N′)nickel(II) naphthalene-2,7-disulfonate
The Ni(II) atom in the title salt, [Ni(C(2)H(8)N(2))(3)](C(10)H(6)O(6)S(2)), is chelated by three ethyl-enediamine ligands in an octa-hedral geometry. The cation and anion are linked by N-H⋯O hydrogen bonds into a three-dimensional network. One of the two -SO(3) groups is disordered over two positions in a 1:1 ratio.
