in the crystal structure of the title polymeric compound, [c42h38n6o33sr5.2(h2o)]n, five independent metal atoms (sr1-sr5) have different coordination environments. the sr1 and sr5 atoms are nine coordinated and feature distorted tricapped trigonal-prismatic and capped square-antiprismatic geometries, respectively. the rest srii atoms have eight coordination numbers. these units are connected v...

Structures are reported here for eight further substituted N-aryl-2-chloronicotinamides, 2-ClC(5)H(3)NCONHC(6)H(4)X-4'. When X = H, compound (I) (C(12)H(9)ClN(2)O), the molecules are linked into sheets by N-H...N, C-H...pi(pyridyl) and C-H...pi(arene) hydrogen bonds. For X = CH(3), compound (II) (C(13)H(11)ClN(2)O, triclinic P1 with Z' = 2), the molecules are linked into sheets by N-H...O, C-H....

The quinolinol derivatives clioquinol (5-chloro-7-iodo-8-quinolinol, Quinoform) and cloxiquine (5-chloro-8-quinolinol) were studied experimentally in the solid state via ³⁵Cl NQR, ¹H-¹⁷O and ¹H-¹⁴N NQDR spectroscopies, and theoretically by density functional theory (DFT). The supramolecular synthon pattern of O-H···N hydrogen bonds linking dimers and π-π stacking interactions were described wit...

The title compound, C(17)H(14)N(2)O, crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the mean planes of the quinoxaline ring system and the phenyl ring in the two mol-ecules are 38.27 (10) and 37.14 (8)°. In the crystal, π-stacking along the b axis contributes to the crystal cohesion with an average distance between quinoxaline units of 3.397 (3) Å. Weak C-H...

Four isostructural, two-dimensional (2D) grid-type coordination polymers bridged by carboxylate groups, namely [Co(8-qoac)(HCOO)] (1 x Co), [Mn(8-qoac)(HCOO)] (1 x Mn), [Co(8-qoac)(CH3COO)] (2 x Co) and [Mn(8-qoac)(CH3COO)] (2 x Mn) (8-qoacH = quinoline-8-oxy-acetate acid), were constructed to study the modulation effects of spin carriers and interlayer interactions on the magnetic behaviours. ...
