Tetra­kis(μ2-phenyl­acetato-κ2 O:O′)bis­[(isoquinoline-κN)copper(II)]

In the title centrosymmetric binuclear CuII complex, [Cu2(C8H7O2)4(C9H7N)2], the two Cu cations are bridged by four carboxyl­ate groups of the phenyl­acetate anions; each Cu cation is further coordinated by an isoquinoline ligand to complete the distorted CuO4N square-pyramidal geometry. The Cu cation is displaced by 0.2092 (8) Å from the basal plane formed by the four O atoms. Within the dinuclear mol­ecule, the Cu⋯Cu separation is 2.6453 (6) Å. Although a parallel, overlapped arrangement of isoquinoline ligands exists in the crystal structure; the longer face-to-face distance of 3.667 (5) Å suggests there is no π–π stacking between isoquinoline ring systems

2-Bromo-4-chloro-6-(cyclo­hexyl­imino­meth­yl)phenol

The title compound, C13H15BrClNO, was prepared by the condensation of equimolar quanti­ties of 3-bromo-5-chloro­salicyl­aldehyde with cyclo­hexyl­amine in methanol. There is an intra­molecular O—H⋯N hydrogen bond in the mol­ecule. The cyclo­hexyl ring adopts a chair conformation

Biomimetic Polymer Film with Brilliant Brightness Using a One‐Step Water Vapor–Induced Phase Separation Method

The scales of the white Cyphochilus beetles are endowed with unusual whiteness arising from the exceptional scattering efficiency of their disordered ultrastructure optimized through millions of years of evolution. Here, a simple, one‐step method based on water vapor–induced phase separation is developed to prepare thin polystyrene films with similar microstructure and comparable optical performance. A typical biomimetic 3.5 µm PS film exhibits a diffuse reflectance of 61% at 500 nm wavelength, which translates into a transport mean free path below 1 µm. A complete optical characterization through Monte Carlo simulations reveals how such a scattering performance arises from the scattering coefficient and scattering anisotropy, whose interplay provides insight into the morphological properties of the material. The potential of bright‐white coatings as smart sensors or wearable devices is highlighted using a treated 3.5 µm film as a real‐time sensor for human exhalation

Dichloridobis(isoquinoline-κN)zinc(II)

In the title compound, [ZnCl2(C9H7N)2], the ZnII cation is coordinated by two Cl− anions and two isoquinoline ligands in a distorted ZnCl2N2 tetra­hedral geometry; the two isoquinoline ring systems are twisted with respect to each other at a dihedral angle of 45.72 (8)°. The parallel isoqiunoline ring systems of adjacent mol­ecules are partially overlapped, with the shorter face-to-face distance of 3.438 (19) Å indicating the existence of weak π–π stacking in the crystal structure

Tetra-μ2-acetato-κ8 O:O′-bis­[(isoquinoline-κN)copper(II)]

In the crystal structure of the title compound, [Cu2(CH3COO)4(C9H7N)2], the CuII cation is coordinated by four acetate anions and one isoquinoline mol­ecule in a distorted square-pyramidal geometry; the CuII cation is 0.1681 (6) Å from the basal coordination plane formed by the four O atoms. Each acetate anion bridges two CuII cations to form the centrosymmetric dinuclear complex. Within the dinuclear mol­ecule, the Cu⋯Cu separation is 2.6459 (4) Å. A parallel arrangement of isoquinoline ligands of adjacent complexes is observed in the crystal structure; the face-to-face distance of 3.610 (10) Å suggests there is no π–π stacking between isoquinoline ring systems
