The crystal structure of [Mn(HIDA) 2 (H 2 O) 2 ] (Tetragonal, P4¯2 1 c (no.114), a = b = 8.10(2)Å, c = 9.605(3)Å, α = β = γ = 90°, Z = 2, R = 0.051, wR 2 = 0.123 for 460 observed reflections) consists of infinite acentric 2D square grids with HIDA — ions as bridging ligands. The 2D grids are interlocked(along the c axis) by hydrogen bonding. The Mn atoms are octahedrally coordinated by four O atoms of four HIDA — ions (d(Mn—O)= 2.183(4)Å ) and two O atoms of two water molecules (d(Mn—OW) = 2.154(5)Å ). The results show that this acentric coordination polymer exhibits strong powder second harmonic generation (SHG) efficiency, ca . 1.9 times that of potassium dihydrogen phosphate, and remarkable thermal stability.
