A Resource Efficient Ising Model‐Based Quantum Sudoku Solver

open access: yesSoftware: Practice and Experience, EarlyView.
ABSTRACT Background Quantum algorithms exploit superposition and parallelism to address complex combinatorial problems, many of which fall into the non‐polynomial (NP) class. Sudoku, a widely known logic‐based puzzle, is proven to be NP‐complete and thus presents a suitable testbed for exploring quantum optimization approaches.

Synthesis and Characterization of a β‐Thio‐δ‐Diimine (BTDDI) and the Related Bimetallic Dimethylaluminium(III) Compound

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
The stepwise transformation of BODDI to BTDDI and further to the aluminium complex is accompanied by a distinct color evolution from colorless to yellow/orange (thermochromic) and finally to an intensely orange species. Thionation of the β‐oxo‐δ‐diimine (BODDI) 3 with P2S5·2Py affords the ditopic β‐thio‐δ‐diimine (BTDDI) 4. Based on 1H NMR spectroscopy

A Trinuclear Manganese(II) Complex Bridged by a Triaminoguanidine‐Based Schiff Base Ligand: Structure and Magnetic Properties

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
A triaminoguanidine‐based Schiff base ligand enables the directed assembly of a trinuclear manganese(II) complex with an almost equilateral triangular topology. Weak antiferromagnetic exchange interactions in combination with axial zero‐field splitting govern the magnetic behavior of the Mn3 core. A triaminoguanidine‐based Schiff base ligand provides a
