چکیده
The asymmetric unit of the title compound, [Eu(NO(3))(C(6)H(5)NO(2))(2)(H(2)O)(4)](NO(3))(2), consists of one-half of the C(2) symmetric coordination cation and one nitrate anion. The eight-coordinated Eu(III) atom is in a distorted dodeca-hedral coordination environment. The coordination cations and nitrate anions are connected via O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network.

The title co-crystal, [Eu(NCS)3(C18H15OP)3][Eu(NCS)2(NO3)(C18H15OP)3], contains two distinct neutral complexes. Each complex has threefold symmetry about its central Eu(3+) ion. As a result, the nitrate-containing mol-ecule contains disorder of its bidentate nitrate and two N-bound thio-cyanate anions, while the [Eu(NCS)3(OPPh3)3] complex is fully ordered. There is a weak π-π stacking inter-act...

In the title compound, {[Nd(NO(3))(C(6)H(5)NO(2))(2)(H(2)O)(3)](ClO(4))(2)·H(2)O}(n), the Nd(III) atom is nine-coordinated by four O atoms from four pyridinium-4-carboxyl-ate ligands, two O atoms from a chelating nitrate anion and three water mol-ecules in a distorted tricapped trigonal-prismatic coordination geometry. Adjacent Nd atoms are linked by the bidentate pyridinium-4-carboxyl-ate liga...

The N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(CH(3)COO)(2)(NO(3))(4)], exist in the zwitterionic form. One heterocycle binds to a metal center whereas the other bridges two metal centers. Each La atom is chelated by an acetate and two nitrate groups and is surrounded by nine O atoms in a distorted tricapped trigonal-prismatic coordination environment. The N-H ...

The title structure, {[Ba(0.71)Sr(1.29)(C(4)HO(4))(4)(H(2)O)(10)]·H(2)O}(n), is built from dimers of edge-sharing monocapped square anti-prisms [(Ba/Sr)O(3)(H(2)O)(6)], in which barium and strontium are statistically disordered [ratio 0.353 (8):0.647 (8)] on the same crystallographic site. Such dimers are connected via bidentate hydrogen squarate groups [HC(4)O(4)](-), leading to chains that pr...

The two independent N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(NO(3))(6)], exist in the zwitterionic form. One of these binds to one metal center, whereas the other bridges two metal centers. The La atom is chelated by three nitrate groups and is surrounded by nine O atoms in a coordination environment based on a distorted monocapped square-anti-prism. The dinu...
