Catena-Poly[1-[(2-fluoro-benzyl-idene)amino]-quinolinium [plumbate(II)-tri-?-iodido]].

ABSTRACT: The title complex, {(C(16)H(12)FN(2))[PbI(3)]}(n), consists of 1-[(2-fluoro-benzyl-idene)amino]-quinolinium cations and a polymeric PbI(3) (-) anion formed by face-sharing PbI(6) octa-hedra. These octa-hedra form straight and regular infinite chains along the b axis. In the asymmetric unit, one cation and one anionic [PbI(3)](-) fragment are observed in general positions. Polymeric chains are produced by the glide plane perpendicular to the a axis.

The one-dimensional organic-inorganic hybrid: catena-poly[bis-[1-(3-ammonio-prop-yl)-1H-imidazolium] [[iodidoplumbate(II)]-tri-?-iodido-plumbate(II)-tri-?-iodido-[iodidoplumbate(II)]-di-?-iodido]].

Project description:The organic-inorganic hybrid, {(C(6)H(13)N(3))(2)[Pb(3)I(10)]}(n), was obtained by the reaction of 1-(3-ammonio-prop-yl)imidazolium triiodide and PbI(2) at room temperature. The structure contains one-dimensional {[Pb(3)I(10)](4-)}(n) polymeric anions spreading parallel to [001], resulting from face-face-edge association of PbI(6) distorted octa-hedra. One of the Pb(II) cations is imposed at an inversion centre, whereas the second occupies a general position. N-H?I hydrogen bonds connect the organic cations and inorganic anions.

catena-Poly[1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium [lead(II)-tri-μ-iodido-lead(II)-tri-μ-iodido]].

Project description:The title compound, {(C(14)H(18)N(2))[Pb(2)I(6)]}(n), consists of discrete 1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium cations and one-dimensional [Pb(2)I(6)](n) anions. The organic cation has an inversion center at the mid-point of the ethane C-C bond. In the anion, the Pb(II) atom is coordinated by six I atoms in a distorted octa-hedral geometry. The I atoms bridge the Pb(II) atoms into a polymeric chain running along [001]. These inorganic chains are separated by the isolated organic cations.

(E)-2-[(2,4,6-Tri-meth-oxy-benzyl-idene)amino]-phenol.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C16H17NO4, with similar conformations but some differences in their bond angles. Each mol-ecule adopts a trans configuration with respect to the methyl-idene C=N bond and is twisted with a dihedral angle between the two substituted benzene rings of 80.52 (7)° in one mol-ecule and 83.53 (7)° in the other. All meth-oxy groups are approximately coplanar with the attached benzene rings, with Cmeth-yl-O-C-C torsion angles ranging from -6.7 (2) to 5.07 (19)°. In the crystal, independent mol-ecules are linked together by O-H⋯N and O-H⋯O hydrogen bonds and a π-π inter-action [centroid-centroid distance of 3.6030 (9) Å], forming a dimer. The dimers are further linked by weak C-H⋯O inter-actions and another π-π inter-action [centroid-centroid distance of 3.9452 (9) Å] into layers lying parallel to the ab plane.

catena-Poly[[[[N'-(4-cyano-benzyl-idene)nicotinohydrazide]silver(I)]-?-[N'-4-cyano-benzyl-idene)nicotinohydrazide]] hexa-fluoridoarsenate].

Project description:In the title compound, {[Ag(C(14)H(10)N(4)O)(2)]AsF(6)}(n), the Ag(I) ion is coordinated by two N atoms from two different pyridyl rings and one N atom from one carbonitrile group of three different N'-(4-cyano-benzyl-idene)nicotinohydrazide ligands in a distorted T-shaped geometry. The Ag-N(carbonitrile) bond distance is significant longer than those of Ag-N(pyrid-yl). The bond angles around the Ag(I) atom are also not in line with those in an ideal T-shaped geometry. One type of ligand acts as the bridge that connects Ag(I) atoms into chains along [01]. These chains are linked to each other via N-H?O hydrogen bonds and Ag?O inter-actions with an Ag?O separation of 2.869?(2)?Å. In addition, the [AsF(6)](-) counter-anions are linked to the hydrazone groups through N-H?F hydrogen bonds. Four of the F atoms of the [AsF(6)](-) anion are disordered over two sets of sites with occupancies of 0.732?(9) and 0.268?(9).

Poly[1,4-bis-(ammonio-meth-yl)cyclo-hexane [di-?-iodido-diiodido-plumbate(II)]].

Project description:The title compound, {(C(8)H(20)N(2))[PbI(4)]}(n), is an inorganic-organic hybrid. The structure is composed of alternate layers of two-dimensional corner-sharing PbI(6) octa-hedra ( symmetry) and 1,4-bis-(ammonio-meth-yl)cyclo-hexane cations ( symmetry) extending parallel to the bc plane. The cations inter-act with the inorganic layer via N-H?I hydrogen bonding in the right-angled halogen sub-type of the terminal halide hydrogen-bonding motif.

catena-Poly[[[N'-(4-cyano-benzyl-idene)nicotinohydrazide)silver(I)]-μ-N'-(4-cyano-benzyl-idene)nicotinohydrazide] hexa-fluorido-phosphate].

Project description:In the title polymer, {[Ag(C(14)H(10)N(4)O)(2)]PF(6)}(n), each Ag(I) ion is coordinated by two N atoms from two pyridyl rings of independent N'-(4-cyano-benzyl-idene)nicotinohydrazide ligands, and one N atom from one carbonitrile group of a symmetry-related ligand in a distorted T-shaped geometry. The ligands exhibit two modes of coordination. One acts as a bridge connecting Ag atoms to form one-dimensional chains along [01]. The other acts as a terminal monodentate ligand, coordinating to Ag through its pyridyl N atom. Two neighbouring anti-parallel chains in the crystal are connected through N-H⋯O hydrogen bonds. Other adjacent chains are packed via Ag⋯O inter-actions, with Ag⋯O separations of 2.876 (2) Å. In addition, PF(6) (-) counter-anions inter-act with the hydrazone groups through N-H⋯F hydrogen bonds. The PF(6) (-) anion is disordered over two sites, with occupancies of 0.773 (8) and 0.227 (8).

Crystal structure of [bis-(2-amino-ethyl-κN)(2-{[4-(tri-fluoro-meth-yl)benzyl-idene]amino}-eth-yl)amine-κN]di-chlorido-copper(II).

Project description:The Cu(II) atom in the title compound, [CuCl2(C14H21F3N4)], adopts a coordination geometry that is between distorted square-based pyramidal and very Jahn-Teller-elongated octa-hedral. It is coordinated by three N atoms from the bis-(2-amino-eth-yl)(2-{[4-(tri-fluoro-meth-yl)benzyl-idene]amino}-eth-yl)amine and two chloride ligands. The two crystallographically unique copper complexes present in the asymmetric unit exhibit noticeable differences in the coordination bond lengths. Considering the Cu(II) atoms as having square-pyramidal geometry, the basal Cu-Cl bond lengths are typical [2.2701 (12) and 2.2777 (12) Å], while the apical distances are considerably elongated [2.8505 (12) and 2.9415 (12) Å]. For each mol-ecule, a Cu(II) atom from inversion-related mol-ecules are in nearby proximity to the remaining axial Cu(II) sites, but the Cu⋯Cl distances are very long [3.4056 (12) and 3.1645 (12) Å], attributable to van der Waals contacts. Nonetheless, these contacts appear to have some structure-directing properties, leading to association into dimers. These dimers associate via stacking of the aromatic rings to form extended zigzag chains.
