N-benzylethylammonium nitrate: a three-dimensional hydrogen-bonded framework comprising substructures in zero, one and two dimensions.

The title compound is a salt, C(9)H(14)N(+).NO(3)(-), in which two N-H...O hydrogen bonds and two C-H...O hydrogen bonds generate a three-dimensional framework structure. The combination of one N-H...O hydrogen bond and one C-H...O hydrogen bond generates a finite (zero-dimensional) centrosymmetric R(4)(4)(14) aggregate containing two cations and two anions; the combination of the two N-H...O hydrogen bonds generates a one-dimensional C(2)(2)(6) chain of alternating cations and anions, and the combination of one N-H...O hydrogen bond and two C-H...O hydrogen bonds generates a two-dimensional sheet of alternating R(4)(4)(14) and R(8)(6)(34) rings.

6-(4-Bromophenyl)-6,7-dihydro-1,3-dioxolo[4,5-g]quinolin-8(5H)-one: bilayers built from N-H...O, C-H...O and C-H...pi(arene) hydrogen bonds.

Molecules of the title compound, C(16)H(12)BrNO(3), exhibit a polarized molecular-electronic structure. A combination of one N-H...O hydrogen bond and one C-H...O hydrogen bond links the molecules into sheets, and pairs of sheets are linked into bilayers by a single C-H...pi(arene) hydrogen bond.

5-Amino-3-tert-butyl-1-(4-nitrophenyl)-1H-pyrazole forms hydrogen-bonded sheets of alternating R2(2)(20) and R6(6)(32) rings.

Molecules of the title compound, C13H16N4O2, are linked by one N-H...O hydrogen bond [H...O = 2.47 A, N...O = 3.326 (2) A and N-H...O = 166 degrees ] and one N-H...N hydrogen bond [H...N = 2.19 A, N...N = 3.063 (2) A and N-H...N = 173 degrees ] into sheets containing alternating R2(2)(20) and R6(6)(32) rings, both types of which are centrosymmetric.

2-Aminobenzimidazolium O-ethyl malonate: eight independent N-H...O hydrogen bonds generate sheets.

The title compound, C(7)H(8)N(3)(+).C(5)H(7)O(4)(-), crystallizes with Z' = 2 in space group P2(1)/c; eight independent N-H.O hydrogen bonds [H.O = 1.75-1.88 A, N.O = 2.699 (2)-2.829 (2) A and N-H.O = 147-179 degrees ] link the four independent ions into sheets.

6-amino-2-(3,4-dimethoxybenzylamino)-3-methyl-5-nitrosopyrimidin-4(3H)-one: hydrogen-bonded sheets form interdigitated bilayers.

Molecules of the title compound, C(14)H(17)N(5)O(4), exhibit a highly polarized molecular-electronic structure. The molecules are linked into sheets by two N-H...O hydrogen bonds [H...O = 2.03 and 2.02 A, N...O = 2.836 (2) and 2.887 (2) A, and N-H...O = 153 and 168 degrees ], augmented by a single C-H...O hydrogen bond [H...O = 2.47 A, C.O = 3.403 (2) A and C-H...O = 166 degrees ]. Pairs of sheets, related by inversion, form bilayers with interdigitated dimethoxybenzyl substituents, weakly linked by a further C-H.O interaction [H...O = 2.50 A, C...O = 3.350 (2) A and C-H...O = 146 degrees].

5-[N-(1H-Benzotriazol-1-ylmethyl)amino]-3-tert-butyl-1-phenylpyrazole: sheets built from N[bond]H...N, C[bond]H...N and C[bond]H...pi(pyrazole) interactions.

In the title compound, C(20)H(22)N(6), the molecules are linked into a chain of rings by N[bond]H...N [H...N 2.16 A, N...N 2.950 (3) A and N[bond]H...N 149 degrees] and C[bond]H...N [H...N 2.55 A, C...N 3.481 (3) A and C[bond]H...N 165 degrees ] hydrogen bonds, and these chains are linked into sheets by means of C[bond]H...pi(pyrazole) interactions.

A comparison of the supramolecular structures of 1-(6-amino-1,3-benzodioxol-5-yl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one and 1-(6-amino-1,3-benzodioxol-5-yl)-3-[4-(N,N-dimethylamino)phenyl]prop-2-en-1-one.

1-(6-amino-1,3-benzodioxol-5-yl)-3-(3,4,5-trimethoxyphenyl)prop-2-en-1-one, C19H19NO6, (I), contains an intramolecular N-H...O hydrogen bond and a weak C-H...O hydrogen bond, which forms a C10 chain motif running parallel to the c axis. The 6-amino-1,3-benzodioxol-5-yl moieties are involved in pi-pi stacking. 1-(6-amino-1,3-benzodioxol-5-yl)-3-[4-(N,N-dimethylamino)phenyl]prop-2-en-1-one, C18H18N2O3, (II), crystallizes with two molecules in the asymmetric unit. The main feature of the supramolecular structure of (II) is the formation of a centrosymmetric hydrogen-bonded tetramer with an R8(4)(16) motif.
