The achiral title compound, C(6)H(4)Cl(2)O(2), crystallizes with O-H⋯O hydrogen bonding linking mol-ecules into layers. Between layers there are chains of Cl⋯Cl⋯Cl inter-actions with alternating distances of 3.274 (2) and 3.742 (2) Å. Augmenting this arrangement there are also C-H⋯Cl (2.97 and 3.17 Å) and Cl⋯π (shortest distances 3.40 and 3.54 Å) inter-actions.

The title compound, C(2)H(10)BCl(2)N(2) (+)·Cl(-) or [BCl(2)(H(3)CNH(2))(2)](+)·Cl(-), is the first crystallographically characterized di(alkyl-amine)-BCl(2) (+) salt. The B atom is tetra-hedrally coordinated by two Cl and two methyl-amine N atoms. In the crystal structure, the cations and anions inter-act via N-H⋯Cl hydrogen bonds (mean H⋯Cl = 2.40 Å), resulting in a layered structure.

Introduction: Knowledge of the distribution of different malocclusions in a geographic location could help orthodontics better know the problems in that region. Moreover, giving awareness about the problem and treatment possibilities can help people. This study aimed to determine types of malocclusion and dental caries in children aged 11 to 14 years in Roudsar, Iran. Materials and Methods: In...

Reactions of 0.5 eq. of the dinuclear complexes [(g-arene)Ru(l-Cl)Cl]2 (arene = g-C6H6, g-p-PrC6H4Me) and [(Cp*)M(l-Cl)Cl]2 (M = Rh, Ir; Cp* = g-C5Me5) with 4,6-disubstituted pyrazolyl-pyrimidine ligands (L) viz. 4,6-bis(pyrazolyl)pyrimidine (L1), 4,6-bis(3-methyl-pyrazolyl)pyrimidine (L2), 4,6-bis(3,5dimethyl-pyrazolyl)pyrimidine (L3) lead to the formation of the cationic mononuclear complexes...

The one-pot reaction of L1SiCl (L1=PhC(NtBu)2) with MesPX2/IsPX2 (X=Cl, Br; Is=2,4,6-iPr3C6H2, Mes=2,4,6-Me3C6H2) in the presence KC8 yielded two phosphasilene compounds L1Si(Cl)=PIs (1) and L1Si(Cl)=PMes (2) interesting Cl?Si=P characteristics. introduction moiety improved reactivity phosphasilene. Furthermore, phosphasilenes 1 2 LSi as well Si=P building units are sensitive to moisture distin...

Regular crystals of the title compound, (C(2)H(8)N)(2)[Sn(CH(3))(2)Cl(4)], were obtained by reacting SnMe(2)Cl(2) with (CH(3))(2)NH·HCl in ethanol in a 1:1 ratio. The Sn atom lies on a center of symmetry and is six-coordinated. It has a distorted octahedral SnC(2)Cl(4) environment with the Cl atoms in cis positions. The Cl atoms are connected to dimethyl-ammonium cations through N-H⋯Cl hydrogen...
