Abstract
. Seven homo- or heterometallic uranyl ion complexes with 1,3-adamantanedicarboxylic acid (H 2 ADC) or 1,3-adamantanediacetic acid (H 2 ADA) have been synthesized under solvo-hydrothermal conditions in the presence of different counterions and organic cosolvents, and characterized by their crystal structure and uranyl emission spectrum. [PPh 3 Me][UO 2 (ADC)(NO 3 )] ( 1 ) crystallizes as a simple monoperiodic chain, but [PPh 4 ] 2 [(UO 2 ) 2 (ADC) 3 ] 2H 2 O ( 2 ) and [PPh 4 ] 2 [(UO 2 ) 2 (ADA) 3 ] ( 3 ) display trough-like monoperiodic assemblies (assembled in pairs in 3 ) in the cavity of which the counterions are located. A similar arrangement is found in [Ni(cyclen)(H 2 O)][(UO 2 ) 2 (ADC) 3 ] H 2 O ( 4 ). Diaxial bonding of Ni II in [(UO 2 ) 2 (ADC) 2 Ni( R,S -Me 6 cyclam)(HCOO) 2 ] CH 3 CN ( 5 ) and [UO 2 obtained from uranyl complexation with 1,3-adamantanedicarboxylate or 1,3-adamantanediacetate under solvo-hydrothermal conditions in the presence of various counterions and organic cosolvents. Several monoperiodic species assume a trough-like shape accommodating the counterions, while heterometallic diperiodic networks are formed through bridging of monoperiodic subunits by nickel(II) cations.
