Crystal structure and physicochemical properties of a new organic condensed phosphate (C7H10NO)3P3O9·4H2O

Bis(2-methoxyanilinium) hexabromidostannate(IV) dihydrate

“…The Br-Sn-Br angles for the Br atoms in cis positions with respect to each other fall in the range of 83.74 4 2). Bond lengths and angles within the cations and dianions are as expected and comparable with those observed in the related compounds (Benali-Cherif et al, 2007;Karoui et al, 2013;Guelmami et al, 2007;Souissi et al, 2011;Smith et al, 2006;Tudela & Khan, 1991;Chouaib et al, 2013). The phenyl ring is practically planar with the greatest deviation from the six-atoms least squares plane being 0.0156 Å.…”

Crystal structure and Hirshfeld surface analysis of 2-aminopyridinium hydrogen phthalate

“…Crystal engineering and the design of supramolecular architectures are of significant interest owing to the technological applications of the resulting materials in the electronics and optical industries. Supramolecular interactions such as chargeassisted hydrogen bonds andinteractions play an important role in crystal engineering as they lead to directional molecular recognition events between molecules or ions, and therefore mediate self-assembly of well-defined supramolecular networks (Guelmami et al, 2007;Prakash et al, 2018;Siva et al, 2017). Amine-based materials are particularly important as they are synthesized by the condensation of the corresponding aldehydes and amines and exhibit strong intermolecular hydrogen bonds between the electronegative acceptor and the N atom of the imine moiety.…”
