Abstract

UO2 (NO3) 2· 6H2O and VO (acac) 2 react with 2-(2′-hydroxylphenyl) benzoxazole (Hpbx) in methanol to give [UO2 (pbx) 2 (CH3OH)](1) and [VO (pbx) 2](2). Complex 1 shows a distorted pentagonal bipyrimidal geometry, characteristic for the coordination number 7. Reciprocal OH⋯ O interactions between neighbored molecules hold 1 in a pseudo-dimeric association with an inversion center. Complex 2 achieves a distorted octahedral geometry ...
