Poly[?-2,3-dihydroxy-propan-1-olato-sodium].

ABSTRACT: The Na(+) cation in the title compound, [Na(C(3)H(7)O(3))](n) or Na[H(2)gl], is coordinated by five O atoms leading to a distorted trigonal-bipyramidal geometry. The negatively charged O atom of the glycerolate anion is in an equatorial position, and the O atom of the hydroxo group, attached to the secondary C atom, occupies an axial position completing a five-membered non-planar chelate ring; this defines the asymmetric unit. The Na(+) cation is coordinated by three other symmetry-related monodentate H(2)gl(-) ligands, so that each H(2)gl(-) ligand is bonded to four Na(+) ions. The H(2)gl(-) ligands are connected via strong O-H?O hydrogen bonds and these, together with the Na?O inter-connections, are responsible for the formation of polymeric sheets which propagate in the directions of the b and c axes.

Poly[?-(1,3-dihy-droxy-propan-2-olato)-potassium].

Project description:The asymmetric unit of the title compound, [K(C(3)H(7)O(3))](n) or K[H(2)gl](n), common name potassium glycerolate, contains half the K(+) cation and half of the glycerolate anion. The other half of the anion is generated through a mirror plane passing through the K atom, and a C, an H and an O atom of the glycerolate ligand. The K(+) ion is coordinated by the O atoms of the OH groups, leading to a six-membered chelate ring that adopts a very distorted boat conformation. The negatively charged O atom of the glycerolate anion, [H(2)gl(-)], is found in the flagpole position and forms an ionic bond with the K(+) ion. The O atoms of the hydroxo groups are coordinated to two K(+) ions, whereas the negatively charged O atom is bonded to one K(+) ion. The K(+) ion is coordinated by three other symmetry-related monodentate H(2)gl(-) ligands, so that each H(2)gl(-) ligand is bonded to two K(+) ions, and the potassium has a seven-coordinate environment. The H(2)gl(-) ligands are connected via a strong O-H?O hydrogen bond and, together with the K?O inter-connections, form polymeric sheets which propagate in the directions of the a and b axes.

Poly[aqua-[?-4-(4-chloro-phen-yl)-2-thioxo-2,3-dihydro-thia-zol-3-olato]-sodium(I)].

Project description:The packing of the title compound, [Na(C(9)H(5)ClNOS(2))(H(2)O)](n), in the crystal structure occurs by pairwise attachment of +sc- and -sc-arranged 4-(4-chloro-phen-yl)-2-thioxo-2,3-dihydro-thia-zol-3-olate subunits via S to sodium. Water mol-ecules that are bound in the axial position of the distorted octa-hedral coordination octahedron give rise to a stereogenic center at sodium.

(S)-1-Hydroxy-propan-2-aminium (2R,3R)-3-carb-oxy-2,3-dihydroxy-propanoate monohydrate.

Project description:The chiral title compound, C(4)H(10)NO(+)·C(4)H(5)O(6) (-)·H(2)O, is a hydrated mol-ecular salt in which the tartaric acid has transferred one proton to the (S)-2-amino-propan-1-ol mol-ecule. The crystal structure is stabilized by a three-dimensional network of N-H?O and O-H?O hydrogen bonds. The absolute configuration was assigned on the basis of the starting materials.

Guanidinium 3-carb-oxy-2,3-dihydroxy-propanoate monohydrate.

Project description:In the title hydrated salt, CH(6)N(3) (+)·C(4)H(5)O(6) (-)·H(2)O, the deprotonated carboxyl group is disordered over two positions with a site-occupancy ratio of 0.945?(3):0.055?(3). The bond lengths in the guanidinium cation are inter-mediate between normal C-N and C=N bond lengths, indicating significant delocalization in this species. In the crystal structure, anions and water mol-ecules are linked into sheets parallel to the ab plane by inter-molecular O-H?O hydrogen bonds. The linking of the anions and water mol-ecules with the cations by inter-molecular N-H?O hydrogen bonds creates a three-dimensional network.

Tetra-kis[μ<sub>2</sub>-1,1,1,3,3,3-hexa-fluoro-2-(tri-fluoro-meth-yl)propan-2-olato]tetra-kis-(μ<sub>3</sub>-2-methyl-propan-2-olato)octa-copper(I).

Project description:The title compound, [Cu8(C4H9O)4(C4F9O)4], crystallizes in the monoclinic space group, P21/n and contains a self-assembly of two C16H18Cu4F18O4 units linked by bridging tert-butyl groups [Cu-O bonds of length 2.3779 (15) and 2.4248 (15) Å], generating a centrosymmetric dimer. The asymmetrical unit, C16H18Cu4F18O4, contains an almost square-planar arrangement of the four Cu atoms linked by bridging tert-butyl and perfluorinated tert-butyl groups with Cu-Cu distances ranging from 2.7108 (4) to 2.7612 (4) Å and Cu -Cu-Cu angle values close to 90° [ranging from 89.459 (10)° to 90.025 (11)°]. These dimers are further linked by weak C-H⋯F and F⋯F inter-actions. As is commonly encountered in perfluorinated tert-butyl groups, one of the CF3 groups is disordered and was refined with two equivalent conformations with occupancies of 0.74 (3) and 0.26 (3).

1,4-Dihydroxy-quinoxaline-2,3(1H,4H)-dione.

Project description:The asymmetric unit of the title compound, C(8)H(6)N(2)O(4), contains one half-mol-ecule; a twofold rotation axis bisects the molecule. The quinoxaline ring is planar, which can be attributed to electron delocalization. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the mol-ecules into R(2) (2)(10) motifs, leading to layers, which inter-act via phen-yl-phenyl inter-actions (C?C distances in the range 3.238-3.521?Å).

Bis(?-propan-2-olato-?O:O)bis-[chlor-ido(propan-2-ol-?O)bis-(pro-pan-1-ol-ato-?O)tin(IV)].

Project description:The binuclear centrosymmetric title compound, [Sn(2)(C(3)H(7)O)(6)Cl(2)(C(3)H(8)O)(2)], exhibits an edge-shared double octahedral exhibits an edge-shared octa-hedral structure, which is distorted owing to the presence of asymmetric intra-molecular hydrogen bonds between the axially coordinated isopropanol and isopropoxide ligands. The H atom of the hy-droxy group is located nearer to an isoprop-oxy group with the longest Sn-O bond [2.1789?(17)?Å].

N'-(2,3-Dimethoxy-benzyl-idene)-2,4-dihydroxy-benzohydrazide.

Project description:In the title compound, C(16)H(16)N(2)O(5), the dihedral angle between the two benzene rings is 8.5?(3)° and the mol-ecule adopts an E configuration with respect to the C=N bond. There is an intra-molecular N-H?O hydrogen bond in the mol-ecule, which generates an S(6) ring. In the crystal, mol-ecules are linked through inter-molecular O-H?O hydrogen bonds, forming layers parallel to the bc plane.

Poly[tetrakis(?-1,1,1,3,3,3-hexafluoropropan-2-olato)iron(II)dipotassium].

Project description:The title compound, [K2Fe{OCH(CF3)2}4] n , was formed from the reaction of potassium hexa-fluoro-isopropoxide with iron(II) chloride in toluene. The Fe(II) atom has a highly distorted tetra-hedral coordination environment. All four of the non-equivalent hexa-fluoro-isoprop-oxy O atoms link the Fe(II) atoms to one of the K(+) atoms in an alternating chain of Fe-O-K-O fused four-membered rings, with K-Fe distances of 3.715?(2) and 3.717?(2)?Å. This K(+) atom is also bridged to eight of the F atoms. The other K(+) atom is bonded to only two of the O atoms, but has seven short K?F contacts, one of which links the chains into a three-dimensional arrangement. Weak hydrogen bonding between the lone H atoms on the hexa-fluoro-isoprop-oxy groups and F atoms is also present. The crystal studied was refined as an inversion twin.
