(Dimethyl-phosphor-yl)methanaminium chloride.

ABSTRACT: The crystal structure of the title salt, C(3)H(11)NOP(+)·Cl(-), is primarily built from centrosymmetric dimers of two cations, connected head-to-tail by two charge-supported strong N-H?O hydrogen bonds, with a graph-set descriptor R(2) (2)(10). The chloride counter-anions connect these dimeric cationic units into chains along the a-axis direction.

The crystal structure of the title salt, C(3)H(11)NOP(+)·Cl(-), is primarily built from centrosymmetric dimers of two cations, connected head-to-tail by two charge-supported strong N-H⋯O hydrogen bonds, with a graph-set descriptor R(2) (2)(10). The chloride counter-anions connect these dimeric cationic units into chains along the a-axis direction. ...[more]

(Di-methyl-phosphor-yl)methanaminium nitrate.

Project description:In the crystal of the title salt, C3H11NOP(+)·NO3 (-), dicationic inversion dimers are head-to-tail connected by a pair of strong N-H?O hydrogen bonds. The resulting graph-set descriptor of this ring system is R 2 (2)(10). The nitrate counter-anions connect the dicationic dimers via N-H?O hydrogen bonds, forming two-dimensional networks in the bc plane.

(Di-methyl-phosphor-yl)methanaminium iodide-(di-methyl-phosphor-yl)methan-amine (1/1).

Project description:The asymmetric unit of the title structure, C3H11NOP(+)·I(-)·C3H10NOP, consists of one (di-methyl-phosphor-yl)methanamine (dpma) mol-ecule, one (di-methyl-phosphor-yl)methanaminium (dpmaH) ion and one iodide counter-anion. In the crystal, medium-strong to weak N-H?O and N-H?N hydrogen bonds connect dpmaH cations and dpma mol-ecules into strands along [001]. The iodide counter-anions form only very weak hydrogen bonds. The crystal used for the diffraction study was found to be an inversion twin with a ratio of 0.83?(2):0.17?(2). The title structure is isotypic to that of dpmaH[ClO4]·dpma [Buhl et al. (2013 ?). Crystals 3, 350-362].

(4-Meth-oxy-phen-yl)methanaminium chloride.

Project description:In the crystal structure of the title salt, C(8)H(12)NO(+)·Cl(-), the methoxy group of the cation is co-planar with the phenylene moiety with an r.m.s. deviation from the mean plane of only 0.005 Å. The ammonium N atom deviates from this plane by 1.403 (1) Å. In the crystal, the (4-meth-oxy-phen-yl)methan-aminium cations and chloride anions are linked by N-H⋯Cl and C-H⋯O hydrogen bonds, resulting in an open framework architecture with hydrogen-bonded ammonium groups and chloride anions located in layers parallel to (011), separated by more hydrophobic layers with interdigitating anisole groups.

(Di-methyl-phosphor-yl)methanaminium hydrogen oxalate-oxalic acid (2/1).

Project description:The reaction of (di-methyl-phosphor-yl)methanamine (dpma) with oxalic acid in ethanol yielded the title solvated salt, C3H11NOP(+)·C2HO4 (-)·0.5C2H2O4. Its asymmetric unit consists of one dpmaH(+) cation, one hydrogen oxalate anion and a half-mol-ecule of oxalic acid located around a twofold rotation axis. The H atom of the hydrogen oxalate anion is statistically disordered over two positions that are trans to each other. The hydrogen oxalate monoanion is not planar (bend angle ∼16°) whereas the oxalic acid molecule shows a significantly smaller bend angle (∼7°). In the crystal, the components are connected by strong O-H⋯O and much weaker N-H⋯O hydrogen bonds, leading to the formation of layers extending parallel to (001). The structure was refined from a racemically twinned crystal with twin components in an approximate 1:1 ratio.

(4-Chloro-phen-yl)methanaminium chloride hemihydrate.

Project description:In the title hydrated salt, C(7)H(9)ClN(+)·Cl(-)·0.5H(2)O, the water O atom lies on a crystallographic twofold axis. In the crystal, the monoprotonated 4-chloro-benzyl-ammonium cation forms N-H?Cl and N-H?O hydrogen bonds and the water mol-ecule forms O-H?Cl hydrogen bonds, generating layers lying parallel to the bc plane.

rac-{[2-(Diphenyl-thio-phosphor-yl)ferrocen-yl]meth-yl}dimethyl-ammonium diphenyl-dithio-phosphinate.

Project description:2-(Diphenyl-thio-phosphino)dimethyl-amino-methyl-ferrocene is a key inter-mediate in the synthesis of various ferrocenyl ligands. During one such synthesis, the title compound, [Fe(C(5)H(5))(C(20)H(22)NPS)](C(12)H(10)PS(2)), was isolated as a by-product. It is built up by association of (2-(diphenyl-phosphino)ferrocen-yl)meth-yl)dimethyl-ammonium cations and diphenyl-phosphino dithio-ate anions. N-H?S, C-H?S and C-H?? inter-actions link the anions and cations. Each anion-cation pair is linked two by two through C-H?? inter-actions, forming pseudo dimers.

Pseudosymmetric fac-di-aqua-trichlorido[(di-methyl-phosphor-yl)methanaminium-?O]manganese(II).

Project description:In the title compound, [Mn(C3H11NOP)Cl3(H2O)2], the Mn(II) metal center has a distorted o-cta-hedral geometry, coordinated by the three chloride ligands showing a facial arrangement. Two water mol-ecules and the O-coordinated dpmaH cation [dpmaH = (di-methyl-phosphor-yl)methanaminium] complete the coordination sphere. Each complex mol-ecule is connected to its neighbours by O-H?Cl and N-H?Cl hydrogen bonds. Two of the chloride ligands and the two water ligands form a hydrogen-bonded polymeric sheet in the ab plane. Furthermore, these planes are connected to adjacent planes by hydrogen bonds from the aminium function of cationic dpmaH ligand. A pseudo-mirror plane perpendicular to the b axis in the chiral space group P21 is observed together with inversion twinning [ratio = 0.864?(5):0.136?(5)].

trans-Dichlorido-tetra-kis-[(di-methyl-phosphor-yl)methanaminium-?O]cobalt(II) tetra-chloridocobaltate(II).

Project description:The asymmetric unit of the title structure, [CoCl2(C3H11NOP)4][CoCl4]2, consists of one half of the trans-dichlorido-tetra-kis-[(di-methyl-phosphor-yl)methanaminium]cobalt(II) tetra-cation lying on an inversion center and one tetra-chloridocobaltate(II) dianion on a general position. Four O-coordinated cationic (di-methyl-phosphor-yl)methanaminium (dpmaH(+)) ligands occupy the equatorial coordination sites, whereas the chloride ligands occupy axial positions of the roughly o-cta-hedral coordination polyhedron of the cobalt metal center. Intra-molecular hydrogen bonds between the aminium groups and the O atom of the phosphoryl groups and additional hydrogen bonds between the aminium groups and the chloride ligands are present. Furthermore, four of the six H atoms not involved in intra-molecular bonding of each cobalt(II) tetra-cation form weak hydrogen bonds to four adjacent tetra-chloridocobaltate(II) counter-anions. By these inter-molecular hydrogen bonds, one-dimensional polymeric strands are formed along the b-axis direction. The hydrogen bonding is analyzed using the graph-set method and the structural similarity with dpmaHCl is discussed.

Bis{4-[(3,5-dimethyl-1H-pyrazol-4-yl)selan-yl]-3,5-dimethyl-1H-pyrazol-2-ium} chloride monohydrate.

Project description:In the title compound, 2C(10)H(15)N(4)Se(+)·Cl(-)·OH(-), a singly protonated mol-ecule of the organic selenide participates in hydrogen bonding with neighboring mol-ecules, forming zigzag chains along [001]. The molecule adapts a cis bridging mode with a C-Se-C angle of 102.13 (15)°. π-π stacking inter-actions are observed between the closest pyrazole rings of neighboring chains [centroid-centroid distance = 3.888 (1) Å] and hydrogen bonding occurs through bridging chloride anions and hydroxide groups. Additionally, O-H⋯Cl hydrogen bonds are formed.

The crystal packing is influenced by O-H?Cl, N-H?Cl, N-H?O, C-H?O and C-H?Cl hydrogen bonds, resulting in structure with an open-framework architecture.
