Abstract
Dihydrobis(tetrazolyl)borate metal compounds of the composition [M(L)2{μ‐H2B(CHN4)2}2]n for M = Mn, Fe, Co, Zn, Cd with L = H2O and for M = Cu with L = NH3 are obtained from metal salts and K[H2B(CHN4)2]. Single‐crystal X‐ray studies reveal the formation of two‐dimensional rhombic grid sheets through the bridging action of the bis(tetrazolyl)borate ligands. Each metal atom is octahedrally coordinated with two trans L ligands and four H2B(CHN4) nitrogen donors. Two additional, hydrogen‐bonded water molecules occupy the rhombic openings in the compounds with M = Mn, Fe, Co, Zn, and Cd. The water of crystallization is held in place through hydrogen bonding from the water ligands and to the nitrogen atoms to give a substructure of parallel kinked water chains. Temperature‐variable magnetic measurements show a Curie‐Weiss behavior for the paramagnetic complexes with M = Mn, Fe, Co, and Cu.Keywords
