One barbiturate and two solvated thio­barbiturates containing the triply hydrogen-bonded ADA/DAD synthon, plus one ansolvate and three solvates of their coformer 2,4-di­amino­pyrimidine

A path to new synthons for application in crystal engineering is the replacement of a strong hydrogen-bond acceptor, like a C=O group, with a weaker acceptor, like a C=S group, in doubly or triply hydrogen-bonded synthons. For instance, if the C=O group at the 2-position of barbituric acid is changed into a C=S group, 2-thio­barbituric acid is obtained. Each of the compounds comprises two ADA hydrogen-bonding sites (D = donor and A = acceptor). We report the results of cocrystallization experiments of barbituric acid and 2-thio­barbituric acid, respectively, with 2,4-di­amino­pyrimidine, which contains a complementary DAD hydrogen-bonding site and is therefore capable of forming an ADA/DAD synthon with barbituric acid and 2-thio­barbituric acid. In addition, pure 2,4-di­amino­pyrimidine was crystallized in order to study its preferred hydrogen-bonding motifs. The experiments yielded one ansolvate of 2,4-di­amino­pyrimidine (pyrimidine-2,4-di­amine, DAPY), C₄H₆N₄, (I), three solvates of DAPY, namely 2,4-di­amino­pyrimidine–1,4-dioxane (2/1), 2C₄H₆N₄·C₄H₈O₂, (II), 2,4-di­amino­pyrimidine–N,N-di­methyl­acetamide (1/1), C₄H₆N₄·C₄H₉NO, (III), and 2,4-di­amino­pyrimidine–1-methyl­pyrrolidin-2-one (1/1), C₄H₆N₄·C₅H₉NO, (IV), one salt of barbituric acid, viz. 2,4-di­amino­pyrimidinium barbiturate (barbiturate is 2,4,6-trioxopyrimidin-5-ide), C₄H₇N₄⁺·C₄H₃N₂O₃⁻, (V), and two solvated salts of 2-thio­barbituric acid, viz. 2,4-di­amino­pyrimi­dinium 2-thio­barbiturate–N,N-di­methyl­formamide (1/2) (2-thio­barbiturate is 4,6-dioxo-2-sulfanylidenepy­rimidin-5-ide), C₄H₇N₄⁺·C₄H₃N₂O₂S⁻·2C₃H₇NO, (VI), and 2,4-di­amino­pyrimidinium 2-thio­barbiturate–N,N-di­methyl­acetamide (1/2), C₄H₇N₄⁺·C₄H₃N₂O₂S⁻·2C₄H₉NO, (VII). The ADA/DAD synthon was succesfully formed in the salt of barbituric acid, i.e. (V), as well as in the salts of 2-thio­barbituric acid, i.e. (VI) and (VII). In the crystal structures of 2,4-di­amino­pyrimidine, i.e. (I)–(IV), R₂²(8) N—H...N hydrogen-bond motifs are preferred and, in two structures, additional R₃²(8) patterns were observed.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. The used target distances were 1.52 (1) Å for d(C1X/Y,C2X/Y) and d(C31X/Y,C2X'/Y'), 1.25 (1) Å for d(C2X/Y,O21X/Y) and d(C2X'/Y',O21X/Y), 1.30 (1) Å for d(C2X/Y,N3X/Y) and d(C2X'/Y',N3X'/Y'), 1.47 (1) Å for d(N3X/Y,C31X/Y), d(N3X/Y,C32X/Y), d(N3X'/Y',C1X/Y) and d(N3X'/Y',C32X/Y), 2.42 (2) Å for d(O21X/Y,C1X/Y) and d(O21X/Y,C31X/Y), 2.23 (2) Å for d(O21X/Y,N3X/Y) and d(O21X/Y,N3X'/Y'), 2.41 (2) Å for d(C1X/Y,N3X/Y) and d(C31X/Y,N3X'/Y'), 2.41 (2) Å for d(C2X/Y,C31X/Y) and d(C2X'/Y',C1X/Y), 2.43 (2) Å for d(C2X/Y,C32X/Y) and d(C2X'/Y',C32X/Y), and 2.52 (2) Å for d(C31X/Y,C32X/Y) and d(C1X/Y,C32X/Y).

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Special details

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. The used target distances were 1.52 (1) Å for d(C1X/Y,C2X/Y) and d(C31X/Y,C2X'/Y'), 1.25 (1) Å for d(C2X/Y,O21X/Y) and d(C2X'/Y',O21X/Y), 1.30 (1) Å for d(C2X/Y,N3X/Y) and d(C2X'/Y',N3X'/Y'), 1.47 (1) Å for d(N3X/Y,C31X/Y), d(N3X/Y,C32X/Y), d(N3X'/Y',C1X/Y) and d(N3X'/Y',C32X/Y), 2.42 (2) Å for d(O21X/Y,C1X/Y) and d(O21X/Y,C31X/Y), 2.23 (2) Å for d(O21X/Y,N3X/Y) and d(O21X/Y,N3X'/Y'), 2.41 (2) Å for d(C1X/Y,N3X/Y) and d(C31X/Y,N3X'/Y'), 2.41 (2) Å for d(C2X/Y,C31X/Y) and d(C2X'/Y',C1X/Y), 2.43 (2) Å for d(C2X/Y,C32X/Y) and d(C2X'/Y',C32X/Y), and 2.52 (2) Å for d(C31X/Y,C32X/Y) and d(C1X/Y,C32X/Y).
