摘要

Results of studies performed under the guidance of A. E. Shvelashvili and continued after his decease are analyzed. We consider the coordination compounds containing both mono- and dihydrazides of carbonic acids; in particular, monohydrazides of monobasic benzoic and m-hydroxy benzoic acids (BH=C6H5C(O)NHNH2, m-HBH=HOC6H5C(O)NHNH2) and dihydrazides (DHs) of dibasic acids: malonic, succinic, and glutaric (DM=H2NHN(O)C(CH2)C(O)NHNH2, DS=H2NHN(O)C(CH2)2C(O)NHNH2, and DG=H2NHNOC(CH2)3CONHNH2). Complex compounds of metals with carbonic acid hydrazides are grouped by the ratio between main components (M:Lig = 1:1 and M:Lig = 1:2) and by the gross formulas: M(Lig)XYnH2O and M(Lig)2XYnH2O, where M(II) = Ca, Mn, Fe, Co, Ni, Cu, Zn, and Sr; Lig = BH, m- HBH, DM, DS, DG,X, Y (X, Y = SO2-/4 Cl–, NCS–, ClO4- , I–,NO3- , Br–, and are identical or different acido ligands, n = 0-4. The compounds with carbonic acid dihydrazides are classified by the redistribution criterion of ligands in the –M–DH–M– bonds depending on the M:DH ratio and the nature of the acido ligand. A division into two groups is performed by the criteria: 1) pairs of metal atoms with single bis-bidentate bridges; 2) pairs of metal atoms with double bis-bidentate bridges. Packing features of structural units are revealed in compounds containing residuals of carbonic acid hydrazides.

Shvelashvili的指导下进行的研究结果，并在病逝后继续进行。我们考虑含有碳酸一酰肼和二酰肼的配位化合物;特别是一元苯甲酸和间羟基苯甲酸的单酰肼（BH = C6H5C（O）NHNH2，m-HBH = HOC6H5C（O）NHNH2）和二元酸的二酰肼（DHs）：丙二酸，琥珀酸和戊二酸（DM = H2NHN（O）C（CH2）C（O）NHNH2，DS = H2NHN（O）C（CH2）2C（O）NHNH2，DG = H2NHNOC（CH2）3CONHNH2）。金属与碳酸酰肼的复杂化合物按主要成分之间的比例（M：Lig = 1：1和M：Lig = 1：2）以及以下通式进行分类：M（Lig）XYnH2O和M（Lig）2XYnH2O ，其中M（II）＝ Ca，Mn，Fe，Co，Ni，Cu，Zn和Sr; Lig = BH，m- HBH，DM，DS，DG，X，Y（X，Y = SO2- / 4 Cl–，NCS–，ClO4-，I–，NO3-，Br–，并且相同或不同配体，n = 0-4。带有碳酸二酰肼的化合物根据M：DH比和酸性配体的性质，通过–M–DH–M–键中的配体重新分配标准进行分类。根据以下标准执行两组：1）具有单双双桥的金属原子对; 2）具有双双双桥的金属原子对。在含有碳酸酰肼残留物的化合物中揭示了结构单元的堆积特征。
