Two papers have been published based on the activities of the tutorial sessions conducted during the CIFiesta. The papers have been co-authored by all tutors and students attending each session.

The title coordination polymer was obtained reacting zinc(II) acetate with a tetra計hospho要ate cavitand in DMF. The basic conditions of the reaction medium hydrolysed the cavitand making the phospho要ate group available for coordination to the zinc(II) cation.

Cover illustration: The coordination polymer poly[([mu]4-phenyl計hospho要ato)zinc(II)], [Zn(C6H5O3P)], was obtained serendipitously by reacting zinc(II) acetate with a tetra計hospho要ate cavitand in DMF. The basic conditions of the reaction cleaved the phospho要ate bridges at the upper rim of the cavitand, making them available for reaction with the zinc ions. The coordination polymer can be described as an inorganic layer in which zinc coordinates the oxygen atoms of the phospho要ate groups in a distorted tetra虐edral environment, while the phenyl groups, which are statistically disordered over two orientations, point up and down with respect to the layer. The layers inter苔ct through van der Waals inter苔ctions. Data analysis, structure solution, refinement and validation were conducted as part of a tutorial session during the Crystallographic Information Fiesta held in Naples, Italy, from 29 August to 3 September 2019, and organized by the Italian Crystallographic Association in partnership with the IUCr.
