Crystal structure of poly[?6-adipato-di-aquadi-?2-oxalato-didysprosium(III)].

ABSTRACT: In the title coordination polymer, [Dy2(C6H8O4)(C2O4)2(H2O)2] n , the asymmetric unit consists of one Dy(3+) cation, one half of an adipate anion, two halves of oxalate anions and one coordinating water mol-ecule. The adipate and oxalate ions are located on centres of inversion. The Dy(3+) cation has a distorted tricapped trigonal-prismatic geometry and is coordinated by nine O atoms, four belonging to three adipate anions, four to two oxalate anions and one from an aqua ligand. The cations are bridged by adipate ligands, generating a two-dimensional network parallel to (010). This network is further extended into three dimensions by coordination of the rigid oxalate ligands and is further consolidated by O-H?O hydrogen bonds. A part of the adipate anion is disordered over two positions in a 0.75:0.25 ratio.

Crystal structure of catena-poly[[aquadi-n-propyl-tin(IV)]-?-oxalato].

Project description:The title compound, [Sn(C3H7)2(H2O)(C2O4)] n , represents the first diorganotin(IV) oxalate hydrate to be structurally characterized. The tin(IV) atom of the one-dimensional coordination polymer is located on a twofold rotation axis and is coordinated by two chelating oxalate ligands with two slightly different Sn-O bond lengths of 2.290?(2) and 2.365?(2)?Å, two symmetry-related n-propyl groups with a Sn-C bond lengths of 2.127?(3)?Å, and a water mol-ecule with a Sn-O bond length of 2.262?(2)?Å. The coordination polyhedron around the Sn(IV) atom is a slightly distorted penta-gonal bipyramid with a nearly linear axis between the trans-oriented n-propyl groups [C-Sn-C = 176.8?(1)°]. The bond angles between the oxygen atoms of the equatorial plane range from 70.48?(6)° to 76.12?(8)°. A one-dimensional coordination polymer results from the less asymmetric bilateral coordination of the centrosymmetric oxalate anion, inter-nally reflected by two slightly different C-O bond lengths of 1.248?(3) and 1.254?(3)?Å. The chains of the polymer propagate parallel to [001] and are held together by hydrogen bonds between water mol-ecules and oxalate anions of neighboring chains, leading to a two-dimensional network parallel to (100).

Poly[tetra-aquadi-?(4)-oxalato-lutetium(III)potassium].

Project description:In the title compound, [KLu(C(2)O(4))(2)(H(2)O)(4)](n), the Lu(III) ion lies on a site of [Formula: see text] symmetry in a dodeca-hedron defined by eight O atoms from four oxalate ligands. The K atom lies on another site of the same symmetry and is coordinated by four oxalate O atoms and four O water atoms. The mid-point of the C-C bond of the oxalate group lies on an inversion center. In the packing structure, each oxalate ligand links two Lu(III) and two K atoms, forming a three-dimensional open framework with channels running along [001]. Inter-molecular O-H?O hydrogen bonds occur.

Poly[dimethyl-ammonium [aquadi-?(2)-oxalato-dysprosate(III)] trihydrate].

Project description:The title compound, {(C(2)H(8)N)[Dy(C(2)O(4))(2)(H(2)O)]·3H(2)O}(n), was obtained as an unexpected product under hydro-thermal conditions. The Dy(III) atom is chelated by four oxalate anions, two of which are situated on two different centres of inversion. The distorted tricapped trigonal-prismatic coordination sphere of the Dy(III) atom is completed by a water mol-ecule. The bridging mode of the anions results in the formation of a three-dimensional network with cavities where the ammonium cations and the uncoordinated water mol-ecules reside. The structure is stabilized by numerous N-H?O and O-H?O hydrogen-bonding inter-actions.
