✦ Synopsis

A new one-dimensional gallium phosphate, [NH 3 (CH 2 ) 4 NH 3 ] [Ga(PO 4 )(PO 3 OH)], has been synthesized under solvothermal conditions at 433 K in the presence of 1,4-diaminobutane and the structure determined using room-temperature single-crystal Xray diffraction data (M r " "350.84, orthorhombic, space group Pnaa, a" "9.109(1), b" "11.021(1), c" "11.987(1) A s ; V" " 1203.3 A s 3 , Z" "4, R" "2.84% and R w " "3.54% for 937 observed data (I' '3( (I ))). The structure contains chains of alternating corner sharing GaO 4 and PO 4 tetrahedra between which lie diaminocations. The chains are held together by both strong interchain and chain-diamine hydrogen-bonding interactions giving rise to a new three-dimensional structure. This is compared with the structures of [NH 3 (CH 2 ) 3 NH 3 ][Ga(PO 4 )(PO 3 OH)] and related aluminophosphates.
