    The synthesis, crystal structure and physico-chemical characterization are presented for the piperazinium bis iodate dihydrate. An X-ray investigation has shown that this compound crystallizes in a non-centrosymmetric monoclinic system, space group Pc with the lattice parameters: a = 8.969 (2) Å, b = 6.027 (3)  Å, c = 11.958 (2)  Å; V = 612.7 (3)  Å3 and Z = 2. The structure was solved from 3546 independent reflexions with R1 = 0.053 and wR2 = 0.130. I…O halogen bonds [R22(4) graph-set motif] range between 2.770 (4) and 3.108 (1) Å and connect neighboring IO-3 anions with each other so as to create a bi-dimensional layer parallel to the (b,c) plane. These layers are interconnected via N−H…O and C−H…O, to the piperazinium dication to generate a three-dimensional network

    A new zinc complex of formula [C7H10NO]2 ZnCl4 has been prepared and characterized by X-ray diffraction,  IR and UV-Visible spectroscopies. The complex crystallizes in the monoclinic space group P21/n with a minimal tetrahedral distortion of the ZnCl42- ion and with lattice parameters: a =12.054 (2) Å, b =7.129 (3) Å, c =23.480 (2) Å, β = 100.67 (2)°, V = 1983.03 (1) Å3 and Z = 4. The crystal structure was solved and refined to R = 0.080 and RW = 0.227 with 9611 independent reflections. It can be described by organic layers of p-anisidinium cations held together by C-H…O hydrogen bonds parallel to (010) plane, linked to the inorganic groups of ZnCl42- anions through N-H…Cl hydrogen bonds, electrostatic and Van Der Waals interactions, to form a three-dimensional network

    crystals of a new hybrid compound, (C5H6N2O)2[Co(H2O)6]3(SO4)4.2H2O, were synthesized in aqueous solution and characterized. This compound crystallizes in the triclinic system with the space group P-1, the unit cell :a=6.632(3) Å, b=11.769(5) Å, c=14.210(6) Å, α=67.86(4)°, β=81.32(4)°, γ=85.18(4)° and V=1015.14(8) Å3 . Its crystal structure can be described as a packing of alternated inorganic and organic layers. The different components are connected by a three-dimensional network of O-H...O and N-H...O hydrogen bonds

    This document provides the most recent updates on the technical contributions and research challenges focused in WP3. Each Technology Component (TeC) has been evaluated under possible uniform assessment framework of WP3 which is based on the simulation guidelines of WP6. The performance assessment is supported by the simulation results which are in their mature and stable state. An update on the Most Promising Technology Approaches (MPTAs) and their associated TeCs is the main focus of this document. Based on the input of all the TeCs in WP3, a consolidated view of WP3 on the role of multinode/multi-antenna transmission technologies in 5G systems has also been provided. This consolidated view is further supported in this document by the presentation of the impact of MPTAs on METIS scenarios and the addressed METIS goals.Aziz, D.; Baracca, P.; De Carvalho, E.; Fantini, R.; Rajatheva, N.; Popovski, P.; Sørensen, JH....
