Pentakis(ethylenediammonium) tri-μ-sulfato-bis[trisulfatocerate(IV)] trihydrate
نویسندگان
چکیده
In the cerate(IV) anion of the title salt, (C(2)H(10)N(2))(5)[Ce(2)(SO(4))(9)]·3H(2)O, the two metal atoms are bridged by three sulfate units; each metal atom is itself chelated by other three sulfate units so that the metal atoms exist in nine-coordinate tricapped trigonal-prismatic geometries. The anions, cations and uncoordinated water mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen bonds, forming a three-dimensional network. One of the five cations is disordered with respect to the ethyl-ene portion in a 1:1 ratio.

The Ce(IV) atom in the title salt, {(H(3)NCH(2)CH(2)CH(2)NH(3))(2)[Ce(SO(4))(4)(H(2)O)]·2H(2)O}(n), exists in a monocapped square-anti-prismatic coordination geometry. The water-coordinated metal atom is bonded to four sulfate ions; one of them is monodentate and two function in a chelating mode. The fourth is also chelating but it uses one of the other two O atoms to bind to an adjacent metal ...

The title compound, [Ni(2)(C(12)H(12)N(2)O(4)S(3))(H(2)O)(4)]·2C(3)H(7)NO·3H(2)O, is made up of a centrosymmetric, bimetallic complex containing a 24-membered macrocyclic ring, two dimethyl-formamide and three water solvent mol-ecules. The Ni atom adopts a slightly distorted NiO(6) octahedral geometry arising from two O,O-bidentate ligands and two water molecules. There are inter-molecular O-H⋯...

In the title compound, [Cu(2)(C(12)H(8)N(3)O(2))(2)(C(6)H(8)O(4))(H(2)O)(2)]·3H(2)O, both crystallographically independent Cu atoms are in similar distorted square-pyramidal coordination environments. The dinuclear complex mol-ecules are assembled into one-dimensional supra-molecular chains extending in the [100] direction by hydrogen bonds. Inter-chain hydrogen bonds further link these chains ...

The mol-ecule of the title compound, [Cu(2)(SO(4))(2)(C(11)H(16)N(4))(2)], sits on a center of symmetry. The Cu(II) atom has a distorted trigonal-bipyramidal coordination geometry comprising three O atoms of the two symmetry-related SO(4) (2-) anions and two N atoms from one bis-(3,5-dimethyl-pyrazol-1-yl)methane ligand.

Single crystals of the title compound, {Na(4)[Mo(VI)O(2)(SO(4))(3)]}(n), were grown from a melt of MoO(3) and Na(2)SO(4) in Na(2)S(2)O(7). In contrast to the structure of the isoformular K compound, K(4)[Mo(VI)O(2)(SO(4))(3)], with its monomeric anion, this sodium analogue contains a polymeric anion of the type {[Mo(VI)O(2)(SO(4))(2)-μ-(SO(4))](4-)}(n). The Mo(VI) cations, surrounded by two tig...
