The title stannoxane is a toluene-solvated dimer, [Sn(4)(C(7)H(6)Cl)(8)Cl(2)O(2)(OH)(2)]·C(7)H(8), the tetra-nuclear mol-ecule lying across a center of inversion. The Sn(4)O(4) framework, whose two independent Sn atoms show trigonal bipyramidal coordination, is essentially planar (r.m.s deviation = 0.02 Å). One of the two chloro-benzyl groups of the chloridodiorganyltin unit is disordered over ...

In the title complex, [Pd(2)Cl(4)(C(18)H(22)N(4))]·C(7)H(8), each of the two four-coordinated Pd(II) atoms is in a slightly distorted square-planar geometry, defined by one N atom from the ligand, two bridging Cl atoms and one terminal Cl atom. Inter-molecular C-H⋯π inter-actions between the pyrazole ring H atom and the toluene ring stabilize the crystal structure.

Received: July 28, 2017 Revised: October 17, 2017 Accepted: November 02, 2017 Abstract: Background: Isocyanates are mainly considered respiratory allergens but can also cause contact allergy. Diphenylmethane-4,4′-diamine (4,4′MDA) has been considered a marker for diphenylmethane-4,4′-diisocyanate (4,4′-MDI) contact allergy. Furthermore, overrepresentation of positive patch-test reactions to p-p...
