Poly[?2-aqua-?4-[1-(4-chloro-phen-yl)-4,4,4-tri-fluoro-butane-1,3-dionato]-potassium].

ABSTRACT: In the title compound, [K(C10H5ClO2F3)(H2O)] n , the two independent K(+) ions are located on a twofold rotation axis. For each of the cations, the distorted cubic coordination environment is defined by two F and four O atoms of symmetry-related 1,4-chloro-phenyl-4,4,4-tri-fluoro-butane-1,3-dionate anions and by two O atoms of water mol-ecules. The ?4-bridging character of the anion and the ?2-bridging of the water mol-ecule lead to the formation of layers parallel to (100). The coordinating water mol-ecules are also involved in O-H?O hydrogen bonds that reinforce the mol-ecular cohesion within the layers, which are stacked along [100]. The ?-diketonate anion is not planar, with an angle of 31.78?(10)° between the mean planes of the diketonate group and the chloro-phenyl ring.

Coordinated ethanol mol-ecules are engaged in inter-molecular hydrogen bonds, and the crystal is further stabilized by weak C-H⋯F and C-H⋯π contacts.

Project description:In the title mononuclear coordination complex, [CuFe(C(5)H(5))(C(9)H(5)F(3)O(2))(C(18)H(15)P)(2)], the Cu(I) ion is coordinated by the chelating β-diketonate 1-ferrocenyl-4,4,4-trifluoro-butane-1,3-dione ligand through two O atoms and the two datively bonded triphenyl-phosphane ligands resulting in a distorted tetra-hedral coordination sphere. The Cu(I) ion, together with its chelating butane-1,3-dione group, is mutually coplanar [greatest displacement of an atom from this plane = 0.037 (1) Å], and the Cu(I) ion lies slightly above [0.013 (1) Å] the plane. The overall geometry, including the bond distances and angles within the complex, corresponds to those of other reported copper(I) β-diketon-ates featuring organic groups at the β-diketonate ligand.

Bis[μ-pentane-2,4-dionato(1-)]bis-{aqua-[1,1,1,5,5,5-hexa-fluoro-pentane-2,4-dionato(1-)]cobalt(II)}.

Project description:The title complex, [Co(2)(C(5)HF(6)O(2))(2)(C(5)H(7)O(2))(2)(H(2)O)(2)], is centrosymmetric with a crystallographic inversion center in the middle of the mol-ecule.

Crystal structure of catena-poly[[[tri-aqua-strontium]-di-μ2-glycinato] dibromide].

Project description:In the title coordination polymer, {[Sr(C2H5NO2)2(H2O)3]Br2} n , the Sr(2+) ion and one of the water mol-ecules are located on twofold rotation axes. The alkaline earth ion is nine-coordinated by three water O atoms and six O atoms of the carboxyl-ate groups of four glycine ligands, two in a chelating mode and two in a monodentate mode. The glycine mol-ecule exists in a zwitterionic form and bridges the cations into chains parallel to [001]. The Br(-) counter-anions are located between the chains. Inter-molecular hydrogen bonds are formed between the amino and carboxyl-ate groups of neighbouring glycine ligands, generating a head-to-tail sequence. Adjacent head-to-tail sequences are further inter-connected by inter-molecular N-H⋯Br hydrogen-bonding inter-actions into sheets parallel to (100). O-H⋯Br and O-H⋯O hydrogen bonds involving the coordinating water mol-ecules are also present, consolidating the three-dimensional hydrogen-bonding network.

Crystal structure of poly[[di-μ2-aqua-aqua-sodium] 4-amino-3,5,6-tri-chloro-pyridine-2-carboxyl-ate trihydrate], the sodium salt of the herbicide picloram.

Project description:In the structure of the title complex, {[Na(H2O)3](C6H2Cl3N2O2)·3H2O} n , the sodium salt of the herbicide picloram, the cation adopts a polymeric chain structure, based on μ2-aqua-bridged NaO5 trigonal-bipyramidal complex units which have, in addition, a singly bonded water mol-ecule. Each of the bridges within the chain, which extends parallel to the a axis, is centrosymmetric, with Na⋯Na separations of 3.4807 (16) and 3.5109 (16) Å. In the crystal, there are three water mol-ecules of solvation and these, as well as the coordinating water mol-ecules and the amino group of the 4-amino-3,5,6-tri-chloro-picolinate anion, are involved in extensive inter-species hydrogen-bonding inter-actions with carboxyl and water O atoms, as well as the pyridine N atom. Among these associations is a centrosymmetric cyclic tetra-water R 4 (4)(8) motif, resulting in an overall three-dimensional structure.
