Diaqua­bis(2-chloro­benzoato-κO)bis­(N,N-diethyl­nicotinamide-κN 1)manganese(II)

In the monomeric title complex, [Mn(C7H4ClO2)2(C10H14N2O)2(H2O)2], the MnII atom is located on a crystallographic centre of inversion. The asymmetric unit contains one 2-chloro­benzoate (CB) ligand, one diethyl­nicotinamide (DENA) ligand and one coordinated water mol­ecule, all ligands being monodentate. The four O atoms in the equatorial plane around the Mn atom form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by the two pyridine N atoms of the DENA ligands in the axial positions. The dihedral angle between the carboxyl group and the adjacent benzene ring is 77.9 (11)°, while the pyridine and benzene rings are oriented at a dihedral angle of 45.94 (5)°. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into infinite chains

Crystal structure of trans-(1RS,3RS)-2-N,N'-dimethylaminomethyl-1,3-dithiolane-1,3-dioxide

The title compound, C6H13NO2S2, consists of a five-membered dithiolane ring with one O atom bonded to each S atom and a dimethylaminomethyl group at the 2-position. The asymmetric unit contains three molecules. All of the S1, S2 and C1 atoms are likely to be stereogenic. 2006 © The Japan Society for Analytical Chemistry

N-(p-nitrophenylsulfonyl)-1H-pyrrole

In the title compound, C10H8N2O 4S, the dihedral angle between the pyrrole and benzene rings is 77.9 (1)°. Inter-molecular C - H?O hydrogen bonds stabilize the crystal structure, forming molecular chains extending approximately parallel to the c axis and stacked along the b axis. © 2004 International Union of Crystallography Primed in Great Britain - all rights reserved

N,N-Bis[2-(2-fur-yl)-2-(hydroxy-imino)-eth-yl]aniline

In the crystal structure of the title compound, C18H17N3O4, intra-molecular C - H?O hydrogen bonds cause the formation of two planar five-membered rings, which are also coplanar with the adjacent rings. The oxime units have E configurations and their bond lengths and angles compare well with those in related compounds. In this configuration, the oxime groups are involved as donors in O - H?N hydrogen bonds, linking the mol-ecules into chains extending approximately parallel to the c axis and stacked along the b axis. © International Union of Crystallography 2007

2-methoxymethyl-1,3-dithiepane 1,1,3,3-tetraoxide

The title compound, C7H14O5S2, consists of a seven-membered dithiepane ring with two O atoms bonded to each S atom and a methoxymethyl group at the 2-position. A few close contacts seem to influence the geometry of the dithiepane ring. © 2003 International Union of Crystallography Printed in Great Britain - all rights reserved

Crystal structure of (3R,4R,5R)-3,4,6-tri-O-benzyl-D-glucal
