Surface mo lity such as swarming is thought to precede biofilm forma on during spread of infec on. Popula on of swarming bacteria P. aeruginosa, major infec on in hospitals, will be shown to efficiently propagate as high density waves that move symmetrically as rings within swarms towards the extending tendrils. Mul -scale model simula ons suggested a cell-cell coordina on mechanism of wave pro...

In the title complex, [HgI2(C21H19N5)2], the Hg(II) ion is located on a twofold rotation axis and is coordinated by two I atoms and two N atoms from two (E)-2-{5,5-di-methyl-3-[4-(1H-1,2,4-triazol-1-yl)styr-yl]cyclo-hex-2-enyl-idene}malono-nitrile ligands in a distorted tetra-hedral geometry. In the crystal, the mol-ecules are linked by inter-molecular π-π inter-actions between the triazole and...

The title compound, K[B(5)O(7)(OH)(2)], was obtained from a hydro-thermal reaction. The structure is composed of one K(+) cation and a polyborate (1) (∞)[B(5)O(7)(OH)(2)](-) anion, which consists of two six-membered rings linked by a common BO(4) tetra-hedron. The [B(5)O(7)(OH)(2)](-) units are linked together through two exocyclic O atoms to neighbouring units, forming a helical chain structur...

In the title compound, [Fe(C(5)H(5))(C(18)H(14)NO)], the unsubstituted cyclo-penta-dienyl ring is disordered over two sets of sites with occupancy ratio of 0.55 (1):0.45 (1). One conformation has the rings eclipsed and the other staggered. An intra-molecular C-H⋯O hydrogen bond forms an S(6) ring motif. In the crystal, inter-molecular C-H⋯O and N-H⋯O hydrogen bonds lead to R(2) (1)(7) ring moti...

The asymmetric unit of the title compound, C16H12ClFO2S, contains two independent mol-ecules in which the benzo-furan ring systems are essentially planar, with r.m.s. deviations of 0.007 (1) and 0.013 (1) Å. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds into chains extending along the b axis. These chains are further packed into stacks along the c -axis by S⋯O contacts [3.1...

The title compound, C10H8N2O2·H2O, consists of an N-hy-droxy-quinoline-2-carboxamide mol-ecule in the keto tautomeric form and a water mol-ecule connected through an O-H⋯O hydrogen bond. The N-hy-droxy-quinoline-2-carboxamide mol-ecule has a nearly planar structure [maximum deviation = 0.062 (1) Å] and only the hy-droxy H atom deviates significantly from the mol-ecule plane. In the crystal, π-π...

In the title compound, C(10)H(9)NO(5)S·0.5H(2)O, two geometrically different organic mol-ecules are present. The benzene rings and the carboxyl-ate groups are oriented at dihedral angles of 13.44 (4) and 21.15 (18)°. In both mol-ecules, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring. In the crystal, both moleucles form inversion dimers linked by pairs of O-H⋯O hydrogen bonds to g...

The crystal structure of the title compound, C9H6OS2, represents a new polymorph. The crystal structure was solved in the ortho-rhom-bic space group Pbcn with one half of the mol-ecule in the asymmetric unit. The thio-phene rings are perfectly planar and twisted with respect to each other, showing the mol-ecule to be in an S,O-trans/S,O-trans conformation. In the crystal, C-H⋯O hydrogen bonds c...

In the title pymiridine-2,4-dione derivative, C14H16N2O2S, the dihedral angle between the six-membered rings is 66.69 (10)°. The mol-ecule is twisted about the Cp-S (p = pyrimidine) bond, with a C-S-C-N torsion angle of -19.57 (16)°. In the crystal, adjacent mol-ecules form inversion dimers through pairs of strong N-H⋯O hydrogen bonds, generating an R 2 (2)(8) ring motif. The dimers are connect...

In the title hydrate, C28H42N2O3·H2O, the central 1,3-diazinan-5-ol ring adopts a chair conformation with the two benzyl substituents equatorial and the lone pairs of the N atoms axial. The dihedral angle between the aromatic rings is 19.68 (38)°. There are two intra-molecular O-H⋯N hydrogen bonds, each generating an S(6) ring motif. In the crystal, classical O-H⋯O hydrogen bonds connect the 1,...
