          Abstract

          The crystal structure of a trinuclear Ni II complex with a Schiff base ligand formed in situ from cyste­amine (2-amino­ethane­thiol) and o-vanillin is reported as well results of its anti­bacterial activity screening.

          Abstract

          The title trinuclear nickel(II) complex, [Ni 3(C 10H 11NO 2S) 3]·C 3H 7NO, with a Schiff base ligand formed in situ from 2-amino­ethane­thiol and o-vanillin crystallizes in the ortho­rhom­bic space group Pbca. Its asymmetric unit consists of one neutral Ni 3 L 3 mol­ecule and one DMF solvent mol­ecule. The solid-state organization of the complex can be described as an insertion of the solvent mol­ecules within the crystallographically independent trinuclear Ni II species. Several C—H⋯π edge-to-face inter­actions and π–π stacking inter­actions link the components in the crystal. A first example of a short inter­molecular C—H⋯Ni contact is found. Anti­bacterial in vitro screening revealed that the title compound has anti­bacterial activity, the best effect being against Acinetobacter baumannii.

          publCIF: software for editing, validating and formatting crystallographic information files

          publCIFis an application designed for creating, editing and validating crystallographic information files (CIFs) that are used in journal publication. It validates syntax and dictionary-defined data attributes through internal routines, and also provides a web interface to thecheckCIFservice of the International Union of Crystallography (IUCr), which provides a full crystallographic analysis of the structural data. The graphical interface allows users to edit the CIF either in its `raw' ASCII form (using a text editor with context-sensitive data validation and input facilities) or as a formatted representation of a structure report (using a word-processing environment), as well asviaa number of convenience tools (e.g.spreadsheet representations of looped data). Beyond file and data validation,publCIFprovides access to resources to facilitate preparation of a structure report (e.g.databases of author details, experimental data, standard referencesetc., either distributed with the program or collected during its use), along with tools for reference parsing, spell checking, structure visualization and image management.publCIFwas commissioned by the IUCr, both as free software for authors and as a tool for in-house journal production; the tool for authors is described here. Binary distributions for Linux, MacOS and Windows operating systems are available.

            The exceptionally rich coordination chemistry generated by Schiff-base ligands derived from o-vanillin

            Recent and relevant examples of homo- and heterometallic complexes generated by Schiff base ligands derived from o -vanillin, as well as their properties, are discussed. Ortho -vanillin became very popular in coordination chemistry because of its Schiff bases, which generate a rich variety of complexes, ranging from oligonuclear species to coordination polymers. Some of these organic molecules are particularly useful in metallosupramolecular chemistry for assembling homo- and heterometallic helicates. The Schiff bases obtained using aminoalcohols open the door to the synthesis of homo- and heterometallic clusters with various nuclearities and surprising topologies of the metal centers. Several relevant structural types are reviewed. The heterobinuclear 3d–3d′ and 3d–4f complexes are valuable building-blocks for the synthesis of heterotrimetallic systems. Beyond the richness of this chemistry, the complexes obtained from o -vanillin-based Schiff ligands show interesting properties: magnetism, luminescence, chirality, catalysis, cytotoxicity, and ferroelectricity. This paper reviews recent data that illustrate a very fertile and dynamic research field in coordination chemistry and materials science.
