In the title compound, [Co(C15H11N2O2)2(C2H4O2(C4H12N3)], the CoIII atom exhibits a distorted octa­hedral coordination geometry. There are inter­molecular N—H⋯O hydrogen bonds, forming a three-dimensional network. [ABSTRACT FROM AUTHOR]

In the title compound, C12H11NO3, the mol­ecules have two intra­molecular C—H⋯O hydrogen bonds that define an S(6) S(5) pattern. The mol­ecules are linked by N—H⋯O hydrogen bonds into a centrosymmetric dimer. These dimers are linked by further C—H⋯O hydrogen bonds, so forming a [100] ribbon of R22(8) R44(18)[ R44(20)] rings, a [1 ] chain of alternating R22(8) and R22(22) rings, and an [010] complex chain of R42(18) rings. The combination of the [100] ribbon, the [1 ] chain and the [010] chain results in the formation of a three-dimensional network structure. [ABSTRACT FROM AUTHOR]

The title compound, C17H16Cl2N2, adopts a `vault' conformation. The mol­ecules are linked by a pair of C—H⋯N hydrogen bonds into a centrosymmetric dimer with an R22(18) ring. These dimers are linked by a weak centrosymmetric π–π inter­action into a chain along the [001] direction, and these chains are connected by van der Waals inter­actions, resulting in a three-dimensional network structure.

In the title compound, C17H16N2, the 1,4-diazepine ring adopts a distorted boat conformation, in which the sum of the inter­nal angles is 809°. The mol­ecules are linked by a pair of C—H⋯N hydrogen bonds into a C22(14) chain along the [10 ] direction. [ABSTRACT FROM AUTHOR]

In the title compound, C19H24N2O42+·2Cl−, the cation has mirror symmetry. The ions are linked by N—H⋯Cl and C—H⋯Cl hydrogen bonds into a [01 ] chain with an S21(7) S21(7) R42(14)[ R42(24)] motif, and into a [011] chain with an S21(7) R42(14)[ R42(18)] motif. [ABSTRACT FROM AUTHOR]

The title compound, C50H68N6O8, is a new Schiff base compound synthesized by the condensation reaction of paeonol and N, N, N′, N′-tetra­kis(3-amino­prop­yl)ethyl­ene­diamine in absolute methanol. The mol­ecule possesses a crystallographically imposed centre of symmetry and demonstrates normal values of bond lengths and angles. [ABSTRACT FROM AUTHOR]

Mol­ecules of the title compound, C24H26N4, are linked by C—H⋯N hydrogen bonds, forming a C(5) chain along the [010] direction. Neighboring chains are connected by four C—H⋯π inter­actions, resulting in the formation of a three-dimensional network. [ABSTRACT FROM AUTHOR]

The title complex, [ZnCl2(C19H22N2O4)], is a mononuclear compound; the central zinc ion is coordinated by two Cl− ligands and two N atoms of the bis­(3,4-methyl­enedioxy­benz­yl)­propane-1,3-diamine in a distorted tetra­hedral geometry. The complex adopts a `hawk' conformation. The mol­ecules are linked by pairs of N—H⋯Cl hydrogen bonds into a C22(8) C22(8)[ R22(8) R22(8)] chain of rings along the [001] direction and the mol­ecules are linked by a pair of C—H⋯O and also by a pair of C—H⋯Cl hydrogen bonds into a chain of alternating R22(6) rings and R22(20) rings along the [111] direction. The combination of the [111] chain and the [001] chain generates [1 0] stacks. [ABSTRACT FROM AUTHOR]

The title compound, [Mn2(C7H3NO4)2(H2O)5]·2H2O, has been prepared from the hydro­thermal reaction of mangan­ese(II) chloride tetra­hydrate and pyridine-2,6-dicarboxylic acid. It is isostructural with the analogous CoII, NiII, CuII and ZnII compounds. [ABSTRACT FROM AUTHOR]
