Two heteroatom-containing open-framework aluminophosphates, (C(3)H(4)N(2))(2)FeAl(3)P(4)O(16) and (C(3)H(4)N(2))(2)CrAl(3)P(4)O(16) (denoted as MAPO-CJ50, M = Fe, Cr), have been synthesized by using imidazole as the template under solvothermal conditions. The structure of FeAPO-CJ50 is determined by single-crystal X-ray diffraction, and its analogous structure CrAPO-CJ50 is identified by powder...

Eight coordination polymers (CPs), namely, [Co(?-phsuc)(?-obix)]n (1), {[Co2(?-phsuc)2(?-pbix)1.5]?2H2O}n (2), [Zn(?-phsuc)(?-obix)]n (3), {[Zn(?-phsuc)(?-mbix)]?H2O}n (4), {[Zn(?-phsuc)(?-pbix)]?H2O}n (5), {[Zn(?-phsuc)(?-pbix)]?1.5H2O?CH3OH}n (6), [Cd(?-phsuc)(?-obix)]n (7) and [Cd(?3-phsuc)(?-pbix)0.5]n (8) (phsucH2 = 2-phenylsuccinic acid, obix 1,2-bis((imidazol-1-yl)methyl)benzene, mbix 1,...

The title compound, C 8 H NO 4 + ·NO 3 − ·H 2 O, crystallizes in the same space group ( P 1 / c ) as previously reported dihydrate form [Liang & Zhu (2010). Acta Cryst. E 66 , o667], but with two formula units per asymmetric unit instead of one. In crystal, components are linked into a three-dimensional network by classical intermolecular O—H...O and N—H...O hydrogen bonds π–π stacking inte...

Aromatic π-π stacking inter-actions stabilize the crystal structure of the title compound, C(10)H(12)N(2)O(3), the perpendic-ular distance between parallel planes being 3.7721 (8) Å. The morpholine ring adopts a chair comformation.

In the title compound, C(15)H(8)O, the asymmetric unit contains four independent mol-ecules and crystallizes with aromatic π-π stacking inter-actions[centroid-centroid distances = 3.5326 (18) Å].
