Poly[[bis-(dimethyl-formamide)[?(7)-5,5'-(methyl-enedi-oxy)diisophthalato]dizinc] dimethyl-formamide monosolvate].

ABSTRACT: In the crystal structure of the title coordination polymer, {[Zn(2)(C(17)H(8)O(10))(C(3)H(7)NO)(2)]·C(3)H(7)NO}(n), the mol-ecular build-ing block (MBB), viz. {Zn(2)(CO(2))(4)(C(3)H(7)NO)(2)}, comprises two zinc atoms, each bridged by three carboxyl-ate groups. These two Zn atoms exhibit different coordination environments: a distorted coordination intermediate between trigonal-pyramidal, and square-pyramidal formed by the two coordinated dimethyl-formamide mol-ecules and three carboxylate groups, and a distorted tetra-hedral coordination defined by carboxy-late groups of which three are bidentate bridging and the fourth is a monodentate ligand. Thus, each ligand connects four MBBs, forming the three-dimensional polymer.

Poly[bis-(N,N-dimethyl-formamide)(?-formato)(?(5)-4-oxidoisophthalato)dizinc(II)].

Project description:The title compound, [Zn(2)(CHO(2))(C(8)H(3)O(5))(C(3)H(7)NO)(2)](n), is a three-dimensional metal-organic framework, of which two independent Zn(II) atoms (denoted Zn1 and Zn2) are linked by both 4-oxidoisophthalate and formate bridging ligands. The 4-oxidoisophthalate ligands link two Zn1-type and three Zn2-type atoms, forming a corrugated sheet roughly parallel to the ac plane. The formate ions join two neighboring sheets along the b axis, forming a three-dimensional network. Two independent dimethylformamide ligands are coordinated to separate Zn(II) atoms and fill the voids provided by the framework. Both types of Zn(II) atoms have a distorted trigonal-bipyramidal coordination geometry.

Crystal structure of poly[[[μ4-5-(9H-carbazol-9-yl)isophthalato][μ3-5-(9H-carbazol-9-yl)isophthalato]bis-(di-methyl-formamide)(methanol)dizinc] di-methyl-formamide monosolvate].

Project description:The structure of the polymeric title compound, {[Zn2(C20H11NO4)2(C3H7NO)2(CH3OH)]·C3H7NO} n , comprises carbazolylisophthalate moieties connecting dimetallic tetra-carboxyl-ate zinc secondary building units (SBUs) parallel to [100] and [010], leading to a layer-like arrangement parallel to (001). Each SBU consists of two Zn atoms in slightly distorted tetra-hedral and octa-hedral coordination environments [Zn⋯Zn = 3.5953 (6) Å]. Three carboxyl-ate groups bridge the two Zn atoms in a μ2-O:O' mode, whereas the fourth coordinates through a single carboxyl-ate O atom (μ1-O). The O atoms of two di-methyl-formamide (DMF) and one methanol mol-ecule complete the Zn coordination spheres. The methanol ligand inter-acts with the noncoordinating DMF mol-ecule via an O-H⋯O hydrogen bond of medium strength. Carbazoles between the layers inter-digitate through weak C-H⋯.π inter-actions to form a laminar solid stacked along [010]. Two kinds of C-H⋯π inter-actions are present, both with a distance of 2.64 Å, between the H atoms and the centroids, and a third C-H⋯π inter-action, where the aromatic H atom is located above the carbazole N-atom lone pair (H⋯N = 2.89 Å). Several C-H⋯O inter-actions occur between the coordinating DMF mol-ecule, the DMF solvent mol-ecule, and ligating carboxyl-ate O atoms.

The C and O atoms of the solvent mol-ecule are disordered over two sets of sites of equal occupancy.

Project description:The title compound, (C(2)H(10)N(2))[Ni(C(16)H(14)N(2)O(2))](4)(ClO(4))(2)·C(3)H(7)NO, crystallizes with four Ni(salen) mol-ecules {salen is 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate}, one ethyl-enediammonium cation (actually two half-cations, each located on a center of inversion), two perchlorate anions and one dimethyl-formamide solvent mol-ecule in the asymmetric unit. Each Ni(II) cation in the Ni(salen) complex is four-coordinated by two imine N atoms and two phenolate O atoms from the tetra-dentate ligand. The Ni(salen) units form parallel slipped stacks with Ni?Ni separations of 3.4541?(4) and 3.6442?(6)?Å. The crystal packing is stabilized by inter-molecular hydrogen bonds between the ammonium H atoms and the perchlorate and salen O atoms, which generate a three-dimensional structure.
