چکیده

In the crystal structure of the title salt, [Ag(NH(3))(2)](4)(C(7)H(6)O(7)S(2))(2)·H(2)O, the four independent Ag(I) complex cations all lie on special positions of m site symmetry, as do the two independent 2-hy-droxy-5-methyl-benzene-1,3-disulfonate anions. The Ag(I) cations exist in an almost linear coordination geometry [N-Ag-N = 175.2 (2), 178.08 (16), 175.8 (2) and 178.20 (19)°]. The water mol-ecule is disordered about a mirror plane. Two independent complex cations are linked by an Ag⋯Ag inter-action of 3.3151 (1) Å, furnishing a linear [Ag(NH(3))(2)](n) polycationic chain running along b. The free complex cations, polycationic chain and 2-hy-droxy-5-methyl-benzene-1,3-disulfonate anions inter-act via N-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional network.

The title structure, {[Ba(0.71)Sr(1.29)(C(4)HO(4))(4)(H(2)O)(10)]·H(2)O}(n), is built from dimers of edge-sharing monocapped square anti-prisms [(Ba/Sr)O(3)(H(2)O)(6)], in which barium and strontium are statistically disordered [ratio 0.353 (8):0.647 (8)] on the same crystallographic site. Such dimers are connected via bidentate hydrogen squarate groups [HC(4)O(4)](-), leading to chains that pr...

Crystal structure of 1,3-bis­(3-tert-butyl-2-hy­droxy-5-methyl­benz­yl)-1,3-diazinan-5-ol monohydrate

In the title hydrate, C28H42N2O3·H2O, the central 1,3-diazinan-5-ol ring adopts a chair conformation with the two benzyl substituents equatorial and the lone pairs of the N atoms axial. The dihedral angle between the aromatic rings is 19.68 (38)°. There are two intra-molecular O-H⋯N hydrogen bonds, each generating an S(6) ring motif. In the crystal, classical O-H⋯O hydrogen bonds connect the 1,...
