| Abstract: | A new coordination compound having the formula [La(HMPA)4(NO3)2][Cr(NH3)2(NCS)4] (I), where HMPA is ((CH3)2N)3PO, has been synthesized and studied by X-ray diffraction. Studied crystals of compound I are monoclinic, space group P21/n, a = 15.0360(3) Å, b = 15.1214(3) Å, c = 26.7529(7) Å, β = 100.6610(10)°, V = 5977.7(9) Å3, Z = 2, ρcalc = 1.442 g/cm3, and R1 = 0.0453 for 7344 reflections with Fo ≥ 4σ(Fo). |
