The asymmetric unit of title compound, C(8)H(6)O(4)·2C(4)H(9)NO, contains one half-mol-ecule (an inversion centre in P21/n generates the other half of the molecule) of terephthalic acid (TA) and one mol-ecule of N,N-dimethyl-acetamide (DMAC). The DMAC mol-ecules are linked to TA by strong O-H⋯O hydrogen bonds.
متن کاملUrea–N,N-dimethylacetamide (1/1)
Urea forms a 1:1 solvate with N,N-dimethyl-acetamide (DMA) [systematic name: diamino-methanal-N,N-dimethyl-acetamide (1/1), C(4)H(9)NO·CH(4)N(2)O] with both mol-ecules positioned on a twofold axis, giving rise to rotational disorder of the DMA mol-ecule. The mol-ecules display a layered structure in which urea mol-ecules form hydrogen-bonded ribbons bounded by mol-ecules of solvent.

The title compound, C(26)H(22)N(2)O(2)·2C(4)H(9)NO, crystallizes in an anti C=O orientation. The two amide groups are approximately perpendicular to the naphthalene ring system [dihedral angles = 88.89 (1) and 89.08 (1)°]. Each of the dimethyl-acetamide solvent mol-ecules are disordered over two positions, with occupancies of 0.655 (12):0.345 (12) and 0.531 (13):0.469 (13). The crystal packing ...

In the title zinc(II) coordination polymer, {[Zn(C(14)H(8)O(5))(CH(5)N)(2)]·C(4)H(9)NO}(n), each Zn(II) cation is tetra-hedrally coordinated by two carboxyl-ato O atoms of two oba anions (H(2)oba is 4,4'-oxydibenzoic acid), and two N atoms from two methyl-amine mol-ecules. Each oba anion bridges two Zn(II) cations through the two carboxyl-ate groups in a monodentate fashion, forming one-dimensi...

In the title polymeric complex, [Zn(2)(C(6)H(2)O(4)S)(2)(C(4)H(9)NO)(2)](n), each carboxyl-ate group of the thio-phene-2,5-dicarboxyl-ate dianion bridges a pair of inversion-related dimethyl-acetamide-coordinated Zn(II) atoms, generating a layer motif parallel to (101). The Zn(II) atom shows a distorted square-pyramidal coordination; the apical site is occupied by the O atom of the dimethyl-ace...
