Solid state coordination chemistry of oxomolybdenum organoarsonate materials

The oxomolybdenum-arsonate system was investigated under hydrothermal conditions in the presence of charge-compensating copper(II)-organonitrogen complex cations as secondary building blocks. A series of materials of the Mo/O/As/Cu/ligand family has been prepared and structurally characterized. The architectures of the products reflect the identity of the arsonate component and the organonitrogen ligand, as well as the reaction conditions. The structural versatility of this emerging class of compounds is manifested by the one-dimensional structures of Cu(o-phen)(H(2)O)(2)](2)Mo(6)O(18)(O(3)AsOH)(2)] (1), Cu(terpy)](2)Mo(4)O(13)H(AsO(4))(2)].2H(2)O (2.2H(2)O), Cu(2,2'-bpy)(H(2)O)](2)Mo(6)O(18)(O(3)AsC(6)H(5))(2)].2H(2)O (4.2H(2)O), and Cu(o-phen)(H(2)O)](2)Mo(6)O(18)(O(3)AsC(6)H(5))(2)]].4H(2)O (5.4H(2)O), by the two-dimensional materials Cu(2)(tpyprz)(H(2)O)(2)]Mo(6)O(18)(O(3)AsOH)(2)].2H(2)O (3.2H(2)O), Cu(terpy)](2)Mo(6)O(18)(O(3)AsC(6)H(5))(2)].H(2)O (6.H(2)O), and Cu(2)(tpyprz)]Mo(6)O(18)(O(3)AsC(6)H(5))(2)].2H(2)O (7.2H(2)O), and the molecular clusters Cu(2,2'-bpy)(2)](2)Mo(12)O(34)(O(3)AsC(6)H(5))(4)].2.35H(2)O (8.2.35H(2)O) and Cu(o-phen)(H(2)O)(3)]Cu(o-phen)(2)Mo(12)O(34) (O(3)AsC(6)H(5))(4)].3H(2)O (9.3H(2)O).
